Plain Concrete(普通混凝土)研究综述
Plain Concrete 普通混凝土 - Nonetheless, the presence of PP fibres results in PAFRC mixes having higher tensile strength, abrasion resistance, and skid resistance than plain concrete. [1] Plain concrete (PC) was also studied as reference. [2] Plain concrete has a limited ductility and resistance to cracking (https://theconstructor. [3] The result of this paper shows that the addition of pine needle fibre changed fracture process and improved the mechanical properties compare to that of plain concrete. [4] The seismic pullout strength of the cast-in-place anchor bolts embedded in the plain concrete is a function of the accumulated tensile damage during the load reversals. [5] This study demonstrated the use of KCl separated from chlorine bypass dust (CBD) as an activator for plain concrete. [6] This paper presents a comprehensive analysis of the mesh-dependency issue for both plain concrete and reinforced concrete (RC) members under uniaxial loading. [7] The analysis of strain distribution shows that the maximum compressive strain of RAC in the composite beams is far less than the compressive strains of plain concrete both at peak stress and failure with respect to its stress–strain relationship. [8] The main objectives of this study are to evaluate the effect of geometrical constraints of plain concrete and reinforced concrete slabs on the Wenner four-point concrete electrical resistivity (ER) test through numerical and experimental investigation and to propose measurement recommendations for laboratory and field specimens. [9] Plain concrete was used to cast the dam’s models with 45 Mpa design strength. [10] 03% relative to plain concrete after using both jute fibers and rice husk. [11] 45%) had achieved the highest compressive strength of 37 MPa at 28-days with a significant increment of about 31% compared to plain concrete. [12] Finally, the fracture toughness of fine recycled aggregate concrete is 8% lower than that of plain concrete. [13] Performance of plain concrete with partial replacement of coarse aggregate by rubber chips derived from the waste tire is taken into consideration and an attempt is made to investigate the influence of rubber size on strength, workability, and durability. [14] Compared with plain concrete, the fatigue strength of PFRC could be increased by up to 28. [15] Mortar is an excellent insulator, and reinforcing wire mesh can minimise surface spalling more effectively than plain concrete. [16] 94 times of that of plain concrete when the content of Nano-SiO2 is about 4%. [17] In this regard, silica fume of various contents was added to plain concrete (PC), CaCO3 whisker reinforced cementitious composites (CWRCC) and basalt fiber reinforced cementitious composites (BFRC). [18] Referring to the equation of the full stress-strain curve of plain concrete, the stress-strain constitutive equation of coal gangue fine aggregate concrete was analyzed and studied. [19] In order to further explore the weakening performance of concrete structures in harsh environments such as acid rain and sewage, plain concrete, basalt concrete with 0. [20] Six beams were cast using basalt microfibers, one beam was cast using synthetic fibers and one was cast using plain concrete. [21] The results also showed that the flexural toughness of the improved samples increased significantly (up to 32-fold) with the use of 3% EWRW-F compared to the plain concrete. [22] The experiment results show that the compressive strength and peak strain of CRC are improved under biaxial stress like plain concrete (PC), but due to the weak bond between rubber and cement-based materials, the strength growth rate of CRC is not as much as PC. [23] Compressive strength of concretes incorporating SS is lower than that of plain concrete. [24] In this paper, a strain rate-sensitive isotropic damage model for plain concrete is proposed to describe its nonlinear behavior. [25] , plain concrete and cement blocks. [26] This action is produced by the interaction between both of its components, plain concrete and reinforcing bars. [27] The elasto-plastic characteristics of plain concrete are inevitably affected by the loading rate. [28] In Iraq, the precast concrete panels (flags) are commonly used for roofing and usually produced from plain concrete. [29] The sample damage mode, stress–strain curve and the dynamic compression performance of corroded SFRC were compared with plain concrete. [30] Based on a literature review, four parameters, w/c ratio, binder content, ground granulated blast-furnace slag (GGBS) and fineness of cement, which show a significant influence on the electrical resistivity of plain concrete, were identified, and their influence on the electrical resistivity as well as interaction effects were investigated. [31] To investigate the composite damage effects of explosion based on initial damage caused by penetration, a series of penetration and explosion tests were conducted on plain concrete at different impact velocities, charge masses, and charge locations. [32] Compressive, flexural and splitting strengths were evaluated for plain concrete. [33] 6% for the optimum fibers content and the failure by using corn fibers was a ductile failure compared with plain concrete that gives sudden failure under flexure load, also tensile strength increased by using fibers, more fibers content beyond or more than 2. [34]尽管如此，PP 纤维的存在导致 PAFRC 混合物具有比普通混凝土更高的抗拉强度、耐磨性和防滑性。 [1] 素混凝土 (PC) 也作为参考进行了研究。 [2] 普通混凝土的延展性和抗开裂性有限（https://theconstructor. [3] 研究结果表明，与普通混凝土相比，添加松针纤维改变了断裂过程，提高了力学性能。 [4] 嵌入素混凝土中的现浇地脚螺栓的抗震抗拔强度是荷载反转期间累积拉伸损伤的函数。 [5] 这项研究证明了使用从氯旁路粉尘 (CBD) 中分离出来的 KCl 作为普通混凝土的活化剂。 [6] 本文全面分析了普通混凝土和钢筋混凝土 (RC) 构件在单轴载荷下的网格依赖性问题。 [7] 应变分布分析表明，从应力-应变关系来看，RAC在组合梁中的最大压缩应变远小于素混凝土在峰值应力和破坏时的压缩应变。 [8] 本研究的主要目的是通过数值和实验研究评估素混凝土和钢筋混凝土板的几何约束对温纳四点混凝土电阻率 (ER) 测试的影响，并为实验室和现场试样提出测量建议。 [9] 大坝模型采用素混凝土浇筑，设计强度为 45 Mpa。 [10] 使用黄麻纤维和稻壳后，相对于普通混凝土的 03%。 [11] 45%）在 28 天时达到了 37 MPa 的最高抗压强度，与普通混凝土相比显着增加了约 31%。 [12] 最后，细再生骨料混凝土的断裂韧性比普通混凝土低 8%。 [13] 考虑了用废轮胎产生的橡胶碎片部分替代粗骨料的素混凝土的性能，并试图研究橡胶尺寸对强度、可加工性和耐久性的影响。 [14] 与普通混凝土相比，PFRC 的疲劳强度最高可提高 28 倍。 [15] 砂浆是一种极好的绝缘体，与普通混凝土相比，钢筋网可以更有效地减少表面剥落。 [16] Nano-SiO2含量在4%左右时是普通混凝土的94倍。 [17] 在这方面，在普通混凝土（PC）、CaCO3晶须增强水泥基复合材料（CWRCC）和玄武岩纤维增强水泥基复合材料（BFRC）中添加了不同含量的硅灰。 [18] 参照素混凝土全应力-应变曲线方程，对煤矸石细骨料混凝土的应力-应变本构方程进行了分析研究。 [19] 为了进一步探索混凝土结构在酸雨污水等恶劣环境中的弱化性能，素混凝土、玄武岩混凝土与0. [20] 六根梁用玄武岩微纤维浇铸，一根用合成纤维浇铸，一根用普通混凝土浇铸。 [21] 结果还表明，与普通混凝土相比，使用 3% EWRW-F 的改进样品的弯曲韧性显着提高（高达 32 倍）。 [22] 实验结果表明，在双轴应力作用下，CRC的抗压强度和峰值应变与普通混凝土（PC）一样有所提高，但由于橡胶与水泥基材料之间的结合较弱，CRC的强度增长速度不如普通混凝土（PC）。个人电脑。 [23] 加入 SS 的混凝土的抗压强度低于普通混凝土。 [24] 在本文中，提出了一种应变率敏感的各向同性损伤模型来描述素混凝土的非线性行为。 [25] ，素混凝土和水泥块。 [26] 该作用是由其两个组件（普通混凝土和钢筋）之间的相互作用产生的。 [27] 素混凝土的弹塑性特性不可避免地受到加载速率的影响。 [28] 在伊拉克，预制混凝土板（旗帜）通常用于屋顶，通常由普通混凝土制成。 [29] 将腐蚀的 SFRC 与普通混凝土的样品损伤模式、应力-应变曲线和动态压缩性能进行了比较。 [30] 基于文献综述，确定了对普通混凝土电阻率有显着影响的四个参数，即水灰比、粘合剂含量、磨碎的高炉渣（GGBS）和水泥细度，并确定了它们的影响。对电阻率以及相互作用的影响进行了研究。 [31] 为了研究基于穿透引起的初始损伤的爆炸复合损伤效应，在不同冲击速度、装药质量和装药位置的普通混凝土上进行了一系列穿透和爆炸试验。 [32] 对普通混凝土的抗压、抗弯和劈裂强度进行了评估。 [33] 最佳纤维含量为 6%，与普通混凝土相比，使用玉米纤维的破坏是延性破坏，在弯曲载荷下会突然破坏，使用纤维也会增加抗拉强度，更多的纤维含量超过或超过 2。 [34]
fiber reinforced concrete 纤维增强混凝土
The mechanical properties (compressive strength, splitting tensile strength, flexural strength) and the drying shrinkage of the plain concrete (PC) and macro-synthetic fiber-reinforced concrete (MSFRC) are evaluated. [1] The combination of plain concrete and fiber-reinforced concrete in beams in the form of two-layer composite members can be an efficient solution to improve the flexural behavior, reach the optimum distribution of steel fibers, and reduce the cost of these structural elements. [2] Fiber-reinforced concrete has widely been used due to its advantage that it excels over plain concrete. [3] Different authors conducted studies on fiber reinforced concretes (FRC) with carbon fibres of different lengths and some results showed that concrete mix with homogeneously distributed short fibres in their volume have good strength and ultra-strain compared to normal plain concrete mix. [4] In this research, through reviewing the CEB-FIP MC2010 and ACI 408–12 codes, comparing the reported observations of previous researchers, and conducting 54 pullout tests, it was shown that the bond stress-slip graph between the rebar and fiber-reinforced concrete has a specific pattern different from that of plain concrete, by which the effectiveness of steel fibers in the bond strength can be evaluated with very good accuracy. [5] This was evaluated through 72 bending tests, using plain concrete (control) and fiber-reinforced concrete with volume fibers of 0. [6] For that end, eighteen RC columns with plain concrete and fiber-reinforced concrete, confined and unconfined with CFRP sheets, length to width ratios (L/h) of 4. [7] Compared with the plain concrete specimens, flexural toughness and equivalent flexural strength of macro polypropylene fiber-reinforced concrete (PPFRC) and the hybrid fiber-reinforced concrete (HFRC) increased by 3. [8] By 28 days, the tensile strength of the fiber reinforced concrete is comparable to the plain concrete. [9] The results indicate that Hybrid Fiber Reinforced Concrete (HFRC) has a higher bending strength than the plain concrete. [10] The purpose of this paper is to evaluate plain concrete and fiber-reinforced concrete specimens using ultrasound methods under impact loading. [11]评估了普通混凝土（PC）和宏观合成纤维混凝土（MSFRC）的力学性能（抗压强度、劈裂抗拉强度、抗弯强度）和干缩。 [1] 在梁中以两层复合构件的形式将素混凝土和纤维增强混凝土结合起来，可以有效地改善弯曲性能，达到钢纤维的最佳分布，并降低这些结构元件的成本。 [2] nan [3] 不同的作者对具有不同长度的碳纤维的纤维增强混凝土 (FRC) 进行了研究，一些结果表明，与普通普通混凝土混合料相比，其体积中均匀分布的短纤维混凝土混合料具有良好的强度和超应变。 [4] nan [5] nan [6] nan [7] nan [8] nan [9] nan [10] nan [11]

This paper presents the results of a three-point bending test performed on a TRC formwork superimposed plain concrete beam with prefabricated cracks. [1] A single-edged notch (SEN) beam in a three-point bending test was conducted to evaluate the fracture properties of plain concrete and the repaired of itself. [2] A comprehensive mesoscopic investigation has been conducted to examine the evolution of the fracture process zone (FPZ), using notched plain concrete beams subjected to three-point bending as a generic representation. [3] Acoustic emission (AE), digital image correlation (DIC), and dynamic identification techniques are used to analyze crack formation and propagation in plain concrete prenotched beam specimens subject to three-point bending. [4] Three-point bending tests have been realized on notched-plain concrete instrumented with a sparse array of piezoelectric transducers to validate the proposed approaches and under crack mouth opening displacement (CMOD) control.

The tubular composite column specimens were designed with plain concrete and steel fiber reinforced concrete. [1] The shotcrete strain values of steel fiber reinforced concrete is lower than that of plain concrete, and the shotcrete strain values decreases with the improvement of steel fiber content. [2] The shotcrete strain values of steel fiber reinforced concrete is lower than that of plain concrete, and the shotcrete strain values decreases with the improvement of steel fiber content. [3] It was also concluded that plain concrete monolithic lining as well as layered configuration consisting of Dytherm foam layer between Steel Fiber reinforced Concrete layers, was found to be more vulnerable among the chosen lining materials. [4] Three deep beam samples were used as reference and were cast with (1) plain concrete without stirrups, (2) plain concrete with stirrups and (3) steel fiber reinforced concrete without stirrups. [5]管状复合柱试件采用素混凝土和钢纤维混凝土设计。 [1] 钢纤维混凝土的喷射混凝土应变值低于素混凝土，并且随着钢纤维含量的提高，喷射混凝土应变值减小。 [2] nan [3] nan [4] nan [5]
fibre reinforced concrete 纤维增强混凝土
The objective is to build a model for impact energy using variation in plain concrete and fibre reinforced concrete. [1] Size effect on plain concrete specimens is well known and can be correctly captured when performing numerical simulations by using a well characterised softening function, but in the case of fibre reinforced concrete this is not directly applicable, since an only diagram cannot capture the material behaviour on elements with different size due to dependence of the orientation factor of the fibres with the size of the specimen. [2] Whereas the aim of this paper was to focus on the performance of selected concrete composites, particularly plain concrete and fibre reinforced concrete with polypropylene fibres, exactly at the elevated-temperature state. [3]目标是使用普通混凝土和纤维增强混凝土的变化建立冲击能量模型。 [1] 普通混凝土试件的尺寸效应是众所周知的，并且可以在使用表征良好的软化函数进行数值模拟时正确捕捉到，但在纤维增强混凝土的情况下，这并不直接适用，因为仅有的图表无法捕捉到材料的行为由于纤维的取向因子与试样尺寸的相关性，元件具有不同的尺寸。 [2] nan [3]

Based on the verified model parameters, ABAQUS is used to simulate the four point bending test of steel fiber reinforced 3D printing concrete and plain concrete, focusing on the influence of steel fiber content and notch depth on the load deflection curve.

Jointed Plain Concrete 节理普通混凝土
The sensitivity analysis shows that the overall jointed plain concrete pavements (JPCP) performance prediction by Pavement ME is reasonable. [1] Transverse contraction joints are by far the most common type of joint in jointed plain concrete pavements. [2] On average, twice the number of measurements are needed on jointed reinforced concrete pavements (JRCP) to achieve the same confidence and precision as on jointed plain concrete pavements (JPCP). [3] This study investigated the causes for premature, transverse cracking on urban jointed plain concrete pavements in Illinois. [4] These ARFC courses were placed several years ago on existing jointed plain concrete pavements for highway noise mitigation. [5] This paper presents a mechanistic analysis of the occurrence and extent of premature cracking in jointed plain concrete pavements (JPCPs) by modeling (1) vehicle–pavement interaction, (2) f. [6] For validation, Jointed Plain Concrete Pavements were imaged with the evaluated software and a software assumed to yield standard images. [7] While the program is comprehensive and the data are immense, the study sections are typically only 500 ft in length, which limits the ability to accurately gauge the variability of the distresses in a pavement over a longer length, especially cracking in Jointed Plain Concrete (JPC) slabs. [8] Early-age cracking may occur in high early–strength (HES) concrete repair slabs used for full-depth repairs in jointed plain concrete pavements (JPCPs) due to the early-age volume changes. [9] In the world-wide practice on construction of rigid road pavements significant attention has been given to jointed plain concrete pavements (JPCP) with transverse joints strengthened by dowel bars. [10] Therefore, this study aimed to analyse and evaluate the condition of a jointed plain concrete pavement (JPCP) structure without reinforcement based on the results of deflection and tensile stress. [11] Jointed plain concrete pavements are designed on the basis of edge stresses developed at the bottom of the slab, under environmental and vehicular loads. [12] The design method currently used in Romania for jointed plain concrete pavement design is NP081/2002. [13] Although the design of jointed plain concrete pavements could be solved by commercial software, there is still a need for simple tools to be used in feasibility studies and preliminary cost–benefit analyses. [14] Therefore, a series of proposed calibration coefficients from this research can be useful for industrial applications and design engineers to modify and correct MEPDG overlay design thicknesses on top of hot mix asphalt, and jointed plain concrete pavement surfaces with either hot mix asphalt and warm mix asphalt mixtures. [15] The Pavement ME transverse joint faulting model incorporates mechanistic theories that predict development of joint faulting in jointed plain concrete pavements (JPCP). [16] The AASHTOWare Pavement ME design program was used to simulate the structural performance of typical jointed plain concrete pavement (JPCP) designs for collector roads in Canada. [17] The two most common types of rigid pavements for highways, Continuously Reinforced Concrete Pavement (CRCP) and Jointed Plain Concrete Pavement (JPCP) were considered in the design. [18] Jointed plain concrete pavement (JPCP) is commonly used in roadway construction as an economical choice when distributed steel reinforcement is not necessary. [19] Dowels are located in transverse joints of Jointed Plain Concrete Pavements (JPCP) and they are used to provide load transfer between individual slabs, reduce faulting and improve performance. [20] In jointed plain concrete pavements (JPCPs), the presence of joint fau. [21] In many countries of Latin America, Jointed Plain Concrete Pavements (JPCP) are designed using the American Association of State Highway and Transportation Officials (AASHTO) or the Portland Cement Association (PCA) methods, none of which take explicitly into account the environmental conditions of the specific region where a JPCP will be built. [22]敏感性分析表明，通过 Pavement ME 进行的整体接缝素混凝土路面 (JPCP) 性能预测是合理的。 [1] 横向收缩接缝是迄今为止在接缝普通混凝土路面中最常见的接缝类型。 [2] nan [3] nan [4] nan [5] nan [6] nan [7] nan [8] nan [9] nan [10] nan [11] nan [12] nan [13] nan [14] nan [15] nan [16] nan [17] nan [18] nan [19] nan [20] nan [21] nan [22]

The experimental program includes cyclic diagonal compression tests on fourteen lightly-reinforced concrete panels: one plain concrete panel and thirteen panels reinforced internally with web shear reinforcement-ratio equal to 0. [1] Eleven lightweight concrete mixes were considered, These mixes comprised of; one plain concrete mix (without fibers), two reinforced concrete mixtures of mono fiber (hooked or straight fibers), six reinforced concrete mixtures of double hybrid fibers, and two reinforced concrete mixtures of triple hybrid fibers. [2] Shear capacity tests were conducted on three open sandwich steel plate-concrete composite slabs and one plain concrete slab without a steel plate. [3]实验程序包括对 14 个轻配筋混凝土面板的循环对角压缩试验：1 个素混凝土面板和 13 个内部加固的面板，腹板抗剪配筋率等于 0。 [1] 考虑了 11 种轻质混凝土混合物，这些混合物包括：一种普通混凝土混合物（无纤维），两种单纤维钢筋混凝土混合物（钩状或直纤维），六种双混合纤维的钢筋混凝土混合物，以及两种三重混合纤维的钢筋混凝土混合物。 [2] nan [3]

In this research, high-strength plain concrete was studied under two different frequencies of cyclic compressive stress. [1] A selection of four crimped sleeves of the same type (M16 × 60, M16 × 80, M20 × 70 and M20 × 100) were tested in normal strength plain concrete and SFRC with 30 kg/m3 and 50 kg/m3 fiber content. [2]在这项研究中，研究了两种不同频率的循环压应力下的高强度素混凝土。 [1] 在纤维含量为 30 kg/m3 和 50 kg/m3 的普通强度素混凝土和 SFRC 中测试了四种相同类型的压接套管（M16 × 60、M16 × 80、M20 × 70 和 M20 × 100）。 [2]
Normal Plain Concrete 普通素混凝土
The resulting concrete exhibited lower plastic and hardened densities (2040 and 2117 kg/m 3 respectively) in comparison to normal plain concrete. [1] Different authors conducted studies on fiber reinforced concretes (FRC) with carbon fibres of different lengths and some results showed that concrete mix with homogeneously distributed short fibres in their volume have good strength and ultra-strain compared to normal plain concrete mix. [2]与普通普通混凝土相比，所得混凝土表现出较低的塑性和硬化密度（分别为 2040 和 2117 kg/m 3 ）。 [1] 不同的作者对具有不同长度的碳纤维的纤维增强混凝土 (FRC) 进行了研究，一些结果表明，与普通普通混凝土混合料相比，其体积中均匀分布的短纤维混凝土混合料具有良好的强度和超应变。 [2]

18% compared to the plain concrete mix. [1] The reinforcing efficiency of plastic fibers obtained from shredded plastic waste was tested in plain concrete mixes and experimentally verified in this study. [2] 5 times higher than those of plain concrete mix. [3] For plain concrete mixes, the replacement of NA by RCA resulted in 18, 27, and 5% reductions in the respective design compression strength, elastic modulus, and tensile splitting strength.

[7] In this study, the age-dependent splitting and flexural tensile strength have been investigated by incorporating the various percentages of fly ash in the plain concrete mixes. [8] Test results showed that the substitution of 30% of NA with RCA in plain concrete mixes did not reduce the design cylinder compressive strength (f′c), whereas the use of higher percentages of RCA replacement compromised the fresh and hardened properties of the concrete.

plain concrete beam 普通混凝土梁
In this paper, the probabilistic behavior of plain concrete beams subjected to flexure is studied using a continuous mesoscale model. [1] This paper presents the results of a three-point bending test performed on a TRC formwork superimposed plain concrete beam with prefabricated cracks. [2] In this contribution, an experimental program was undertaken to determine the influence of SHCCs containing high-volume fly ash (HVFA-SHCC) working as a strengthening layer in a plain concrete beam on the flexural behavior of the layered structure, considering the layer thickness, re-curing conditions and curing time. [3] Plain concrete beams with dimensions 400 x 100 x 100 mm3, were tested in the laboratory in an effort to measure the MOR from varied MK composition for each specimen or modified concrete type. [4] A comprehensive mesoscopic investigation has been conducted to examine the evolution of the fracture process zone (FPZ), using notched plain concrete beams subjected to three-point bending as a generic representation. [5] In this study, a continuum-based model was proposed to characterise the flexural performance and damage evolution process of a plain concrete beam under high-cycle fatigue loads. [6] In this study, meso-scale (mm-cm scale) modelling approach is adopted to simulate the behaviour of plain concrete beam under 3-point bending. [7] A total of 47 specimens, including 30 composite beams, 15 plain concrete beams, and 2 bare steel beams were tested.

plain concrete specimen 普通混凝土试样
To accomplish this task, an experimental program was carried out including compression tests on plain concrete specimens exposed to temperatures up to 600 oC and on reinforced concrete stub columns with two different tie configurations heated at a constant rate for up to 120 min. [1] The size effect on plain concrete specimens is well known and can be correctly captured when performing numerical simulations by using a well characterised softening function. [2] Plain concrete specimens are also tested for comparison with the previous ones. [3] Size effect on plain concrete specimens is well known and can be correctly captured when performing numerical simulations by using a well characterised softening function, but in the case of fibre reinforced concrete this is not directly applicable, since an only diagram cannot capture the material behaviour on elements with different size due to dependence of the orientation factor of the fibres with the size of the specimen. [4] These specimens include plain concrete specimens with shear keys, specimens with reinforcement and no shear key, and specimens with both shear keys and reinforcements. [5] Concrete specimens reinforced with mono steel and plastic fibers have decreased in drying shrinkage relative to plain concrete specimens. [6] Compared with the plain concrete specimens, flexural toughness and equivalent flexural strength of macro polypropylene fiber-reinforced concrete (PPFRC) and the hybrid fiber-reinforced concrete (HFRC) increased by 3. [7]为了完成这项任务，我们开展了一项实验计划，包括对暴露在高达 600 oC 温度下的普通混凝土试样和具有两种不同连接配置的钢筋混凝土短柱进行压缩测试，以恒定速率加热长达 120 分钟。 [1] 素混凝土试件的尺寸效应是众所周知的，并且可以在使用良好表征的软化函数进行数值模拟时正确捕获。 [2] nan [3] 普通混凝土试件的尺寸效应是众所周知的，并且可以在使用表征良好的软化函数进行数值模拟时正确捕捉到，但在纤维增强混凝土的情况下，这并不直接适用，因为仅有的图表无法捕捉到材料的行为由于纤维的取向因子与试样尺寸的相关性，元件具有不同的尺寸。 [4] nan [5] nan [6] nan [7]
plain concrete slab 素混凝土板
One of the problems that faces PCC is the allowable spacing for transverse joints in rigid pavements’ plain concrete slabs. [1] Three small plain concrete slabs of surface dimensions of 25 x 50 cm and varying depths of 5 cm, 10 cm, and 20 cm were utilized in this study. [2] In this study, the ballistic perforation resistance of 50 mm thick plain concrete slabs impacted by 20 mm diameter ogive-nose steel projectiles is investigated both experimentally and numerically. [3] An extensive numerical parametric study and an experimental campaign were carried out to evaluate the difference in the shear capacity between composite slabs and equivalent plain concrete slabs with the same overall thickness. [4] Explosive spalling was observed in both plain concrete slabs and in one of the two slabs with steel fibre, this casting some doubts on the use of steel fibre alone against spalling. [5] Shear capacity tests were conducted on three open sandwich steel plate-concrete composite slabs and one plain concrete slab without a steel plate. [6]PCC面临的问题之一是刚性路面的素混凝土板横向接缝的允许间距。 [1] 本研究使用了三个表面尺寸为 25 x 50 厘米、深度为 5 厘米、10 厘米和 20 厘米的小普通混凝土板。 [2] nan [3] nan [4] nan [5] nan [6]
plain concrete column 普通混凝土柱
Compared with plain concrete columns, TRC permanent formwork composite columns can better control the development of cracks and improve the crack development mode under compression. [1] This paper presents the results of an experimental program on plain concrete columns strengthened by FRCM under uniaxial compression loading. [2] In order to investigate the mechanical properties of concrete-filled tube columns with a wider range of confinement factors under axial compression, 14 specimens, including plain concrete columns and concrete-filled PVC, plexiglass and steel tube columns are subjected to axial compression. [3] After a brief state of art about the FRCM system, the paper presents an analytical study on the confinement of plain concrete columns with FRCM composites. [4] Columns in this study are plain concrete columns (having concrete strength of = 24. [5]与普通混凝土柱相比，TRC永久模板组合柱能更好地控制裂缝的发展，改善受压下裂缝的发展方式。 [1] 本文介绍了单轴压缩荷载下 FRCM 加固素混凝土柱的实验结果。 [2] nan [3] nan [4] nan [5]
plain concrete block
Research aims to develop a novel technique for segmental beam fabrication using plain concrete blocks and externally bonded Carbon Fiber Reinforced Polymers Laminates (CFRP) as a main flexural reinforcement. [1] There are three (3) specimens of plain concrete blocks, nine (9) specimens of concrete blocks laterally reinforced with ties (loaded and tested under three different sizes of square steel plate) and nine (9) specimens of concrete blocks laterally reinforced with ties (loaded and tested under three different sizes of circular steel plate). [2] This paper presents a numerical simulation of plain concrete blocks with an unconfined compressive strength of 35 MPA, reinforced by Teflon sheets and subjected to ballistic impact by a high-velocity rigid projectile (960 m/s). [3]plain concrete panel 普通混凝土面板
The experimental program includes cyclic diagonal compression tests on fourteen lightly-reinforced concrete panels: one plain concrete panel and thirteen panels reinforced internally with web shear reinforcement-ratio equal to 0. [1] Comparing Plain concrete panels, FC 650 kg/m3 density has shown the best insulation fire performance, followed by FC 1000 kg/m3 density and AAC. [2] In this article, the response of nine plain concrete panels to an impact of hard projectiles was examined in an experimental study. [3]实验程序包括对 14 个轻配筋混凝土面板的循环对角压缩试验：1 个素混凝土面板和 13 个内部加固的面板，腹板抗剪配筋率等于 0。 [1] 与普通混凝土板相比，FC 650 kg/m3 密度的保温防火性能最好，FC 1000 kg/m3 密度和AAC 次之。 [2] nan [3]
plain concrete mixture 普通混凝土混合物
Further, the average compressive strength of the lightweight plain concrete mixtures fluctuated from 70 to 75% of the compressive strength of normal weight concrete and using admixture improved this ratio. [1] Another innovative concept to improve the tensile strength of the concrete is to add steel fibers into the plain concrete mixture. [2] Experimental results revealed that RCA replacement decreased the compressive strength of plain concrete mixtures with more pronounced reductions being perceived at higher replacement percentages. [3]此外，轻质素混凝土混合物的平均抗压强度在正常重量混凝土抗压强度的 70% 到 75% 之间波动，并且使用外加剂提高了这一比率。 [1] 另一个提高混凝土抗拉强度的创新概念是在普通混凝土混合物中添加钢纤维。 [2] nan [3]
plain concrete sample
To explore the dynamic compressive properties of carbon nanofibers reinforced concrete (CNFC), a 100mm-diameter Split Hopkinson Pressure Bar (SHPB) was used to carry out the impact compression test respectively on the plain concrete samples and the CNFC samples with different fiber volume fractions (respectively, 0. [1] This article illustrates new research regarding long-term deterioration in the tensile strength of plain concrete samples due to sustained stress loading. [2]为探究碳纳米纤维增强混凝土（CNFC）的动态抗压性能，采用直径为100mm的分裂式霍普金森压力棒（SHPB）分别对素混凝土试样和不同纤维体积分数的CNFC试样进行冲击压缩试验。 （分别为 0。 [1] nan [2]
plain concrete pile 普通混凝土桩
But for the cast-in-place plain concrete pile field test research report is rare. [1] Based on the static load of single pile, bearing capacity of composite foundation and in-situ vibration test of foundation bed, it proposed that CFG pile, plain concrete pile and reinforced concrete pile are suitable for diatomite foundation reinforcement. [2]但对于现浇素混凝土桩的现场试验研究报告却很少。 [1] 根据单桩静载、复合地基承载力和基床原位振动试验，提出CFG桩、素混凝土桩和钢筋混凝土桩适用于硅藻土地基加固。 [2]
