Recycled Brick(再生砖)研究综述
Recycled Brick 再生砖 - Six rammed earth materials with alternative stabilisers to cement were studied – three stabilisers combined with a substrate of either crushed limestone or recycled brick and concrete – and contrasted against cement-stabilised crushed limestone. [1] The study was conducted to obtain the relationship between non-destructive and destructive tests in concrete cubes using different ratios of normal stone and recycled brick as a coarse aggregate. [2] Finally, a case study of CDW utilization schemes selection problem is illustrated where the scheme of on-site crushing combined with production of recycled bricks and aggregates is selected as the best option with the sum of the distance Sk between alternatives and the border approximation areas obtained as [0. [3] This work addresses the reuse of recycled bricks aggregates (RBA), coming from faulty bricks for manufacturing prestressed concrete joists, with different percentages of these recycled aggregates, in building floor slabs. [4] An attempt is made in this study to convert this waste into wealth by substituting the recycled brick from demolition waste to granite aggregate in production of the concrete. [5] Agricultural waste (sugarcane bagasse) provided carbon to support denitrification; construction materials (recycled brick and crushed mortar) removed phosphorus (P) from wastewater through adsorption. [6] In addition to this, it was determined which is the viable process for the production of the recycled bricks and the cost of the elaborated bricks, to identify the most optimal for the production in large quantities. [7]研究了六种具有替代水泥稳定剂的夯土材料——三种稳定剂与碎石灰石或再生砖和混凝土的基材相结合——并与水泥稳定的碎石灰石进行对比。 [1] 该研究旨在获得使用不同比例的普通石和再生砖作为粗骨料的混凝土立方体的无损和破坏性测试之间的关系。 [2] 最后,举例说明了CDW利用方案选择问题的案例研究,其中现场破碎与再生砖和骨料生产相结合的方案被选为最佳方案,其中备选方案之间的距离Sk与获得的边界近似区域之和作为[0。 [3] 这项工作解决了再生砖骨料 (RBA) 的再利用问题,这些骨料来自用于制造预应力混凝土托梁的缺陷砖,这些再生骨料的百分比不同,用于建筑楼板。 [4] 本研究试图通过将拆迁废料中的再生砖替换为混凝土生产中的花岗岩骨料,将这种废物转化为财富。 [5] 农业废弃物(甘蔗渣)提供碳以支持反硝化;建筑材料(回收砖和碎砂浆)通过吸附去除废水中的磷(P)。 [6] 除此之外,还确定了生产再生砖的可行工艺和精制砖的成本,以确定最适合大批量生产的工艺。 [7]

In this study, the surface micro-morphology (SMM) of a) four typical natural aggregates, b) recycled concrete aggregate (RCA), and c) recycled brick aggregate (RCB) were investigated using laser scanning confocal microscope, and combined with image analysis technology, roughness theory and fractal theory for quantitative evaluation. [1] Four natural aggregates, one recycled concrete aggregate (RCA), and one recycled brick aggregate (RCB) were used for the experiments, for every aggregate, we investigated two states, the original state and that after the limewater treatment. [2] In this study, natural aggregates (NA) are partially replaced with recycled aggregates such as recycled concrete aggregate and recycled brick aggregate (RBA) in geopolymer previous concrete. [3] It is observed that slump of recycled concrete is significantly influenced by the content in recycled concrete aggregates (RCA), natural sand (NS) and recycled brick aggregates (RBA), respectively. [4]本研究采用激光扫描共聚焦显微镜研究了 a) 四种典型天然骨料、b) 再生混凝土骨料 (RCA) 和 c) 再生砖骨料 (RCB) 的表面微观形貌 (SMM),并结合图像分析技术、粗糙度理论和分形理论进行定量评价。 [1] 四种天然骨料、一种再生混凝土骨料 (RCA) 和一种再生砖骨料 (RCB) 用于实验,对于每种骨料,我们研究了两种状态,即原始状态和石灰水处理后的状态。 [2] nan [3] nan [4]

Due to the limitations of sorting technology, mixed recycled coarse aggregate, which mainly includes recycled concrete coarse aggregate and recycled brick coarse aggregate, accounts for a l. [1] The effect of moisture condition and recycled brick aggregate (RBA) content in recycled coarse aggregate (RCA) on the rheological properties of recycled aggregate concrete (RAC) was examined in this study. [2] The main compositions of recycled coarse aggregate produced from demolition waste of brick-concrete construction are recycled concrete coarse aggregate (RCCA) and recycled brick coarse aggregate (RBCA), called mixed recycled coarse aggregate (MRCA). [3]受分选技术的限制,以再生混凝土粗骨料和再生砖粗骨料为主的混合再生粗骨料占比1。 [1] 本研究考察了再生粗骨料 (RCA) 中水分条件和再生砖骨料 (RBA) 含量对再生骨料混凝土 (RAC) 流变性能的影响。 [2] 砖混建筑拆迁废料产生的再生粗骨料的主要成分是再生混凝土粗骨料(RCCA)和再生砖粗骨料(RBCA),称为混合再生粗骨料(MRCA)。 [3]
recycled brick aggregate 再生砖骨料
Due to the specific gravity of recycled brick aggregate (RBA) is less than that of natural aggregate (NA), the traditional mix proportion design of concrete can not be used. [1] In this study, the surface micro-morphology (SMM) of a) four typical natural aggregates, b) recycled concrete aggregate (RCA), and c) recycled brick aggregate (RCB) were investigated using laser scanning confocal microscope, and combined with image analysis technology, roughness theory and fractal theory for quantitative evaluation. [2] Recycled brick aggregate (RBA) and expanded polystyrene (EPS) are both considered lightweight aggregate. [3] Hence, this research presents an ecofriendly solution to impart self-healing capability to concrete by using bacteria as a healing agent and Recycled Brick Aggregate (RBA) as an immobilizer for bacterial spores. [4] A detailed experimental investigation was carried out to understand the effect of ultrasonic pulse velocity (UPV) in concrete made with recycled brick aggregate (RBA). [5] Four natural aggregates, one recycled concrete aggregate (RCA), and one recycled brick aggregate (RCB) were used for the experiments, for every aggregate, we investigated two states, the original state and that after the limewater treatment. [6] The effect of moisture condition and recycled brick aggregate (RBA) content in recycled coarse aggregate (RCA) on the rheological properties of recycled aggregate concrete (RAC) was examined in this study. [7] The utilization of recycled brick aggregate (RBA) and recycled brick powder (RBP) in cementitious materials helps the reclamation of clay brick waste in construction and demolition waste. [8] Therefore, the objective of the present study is to explore the influence of superplasticizers while adopting recycled brick aggregate (RBA) in the sustainable concrete application as a coarse aggregate. [9] In this study, natural aggregates (NA) are partially replaced with recycled aggregates such as recycled concrete aggregate and recycled brick aggregate (RBA) in geopolymer previous concrete. [10] It is observed that slump of recycled concrete is significantly influenced by the content in recycled concrete aggregates (RCA), natural sand (NS) and recycled brick aggregates (RBA), respectively. [11] This study aimed to investigate the mechanical and electrochemical properties of concrete that uses recycled brick aggregate (RBA) as a substitute for natural coarse aggregate (NCA). [12] The aim of this study is to analyze the deformations produced by shrinkage and creep in concretes in which both the fine and coarse fractions have been replaced with recycled brick aggregates (RBA), and to assess their use in structural applications. [13] Shear strength of reinforced concrete (RC) beams made with recycled brick aggregate (RBA) was investigated. [14] 0789S219 — Recycled brick aggregates are preferable alternatives to natural aggregates for minimizing exploitation of natural resources. [15] This paper aims to investigate the flexural strength, deformation and toughness of steel-polyolefin hybrid fibers reinforced recycled brick aggregates concrete (HFRBAC) through the testing of the beam specimens with the size of 150 × 150 × 550 mm. [16] The experimental results revealed that recycled brick aggregates have lower absorption capacity compared to the virgin brick aggregate. [17] In order to investigate the internal curing effect of recycled brick aggregate (RBA) in recycled aggregate concrete (RAC) and calculate its contribution to the final compressive strength, two RAC groups with different recycled aggregates and 6 replacement ratios (r) under 4 curing ages were tested. [18] This paper reports the results of an experimental program on sustainable cementitious composites made with Recycled Brick Aggregates (RBAs) employed as carriers for Phase-Change Materials (PCMs). [19]由于再生砖骨料(RBA)的比重小于天然骨料(NA),不能采用传统的混凝土配合比设计。 [1] 本研究采用激光扫描共聚焦显微镜研究了 a) 四种典型天然骨料、b) 再生混凝土骨料 (RCA) 和 c) 再生砖骨料 (RCB) 的表面微观形貌 (SMM),并结合图像分析技术、粗糙度理论和分形理论进行定量评价。 [2] 再生砖骨料 (RBA) 和发泡聚苯乙烯 (EPS) 都被认为是轻质骨料。 [3] 因此,本研究提出了一种生态友好的解决方案,通过使用细菌作为愈合剂和再生砖骨料 (RBA) 作为细菌孢子的固定剂,赋予混凝土自愈合能力。 [4] 进行了详细的实验研究,以了解超声波脉冲速度 (UPV) 在用再生砖骨料 (RBA) 制成的混凝土中的影响。 [5] 四种天然骨料、一种再生混凝土骨料 (RCA) 和一种再生砖骨料 (RCB) 用于实验,对于每种骨料,我们研究了两种状态,即原始状态和石灰水处理后的状态。 [6] 本研究考察了再生粗骨料 (RCA) 中水分条件和再生砖骨料 (RBA) 含量对再生骨料混凝土 (RAC) 流变性能的影响。 [7] 再生砖骨料(RBA)和再生砖粉(RBP)在胶凝材料中的利用有助于对建筑和拆迁垃圾中的粘土砖废料进行回收利用。 [8] nan [9] nan [10] nan [11] nan [12] 本研究的目的是分析混凝土的收缩和蠕变产生的变形,其中细碎和粗碎的部分都已被再生砖骨料 (RBA) 取代,并评估它们在结构应用中的用途。 [13] 研究了用再生砖骨料 (RBA) 制成的钢筋混凝土 (RC) 梁的抗剪强度。 [14] 0789S219 — 再生砖骨料是天然骨料的首选替代品,可最大限度地减少对自然资源的开采。 [15] 【摘要】:目的通过对150×150×550mm的梁试件进行试验,研究钢-聚烯烃混合纤维增强再生砖骨料混凝土(HFRBAC)的抗弯强度、变形和韧性。 [16] 实验结果表明,与原始砖骨料相比,再生砖骨料的吸收能力较低。 [17] 为了研究再生砖骨料 (RBA) 在再生骨料混凝土 (RAC) 中的内部养护效果并计算其对最终抗压强度的贡献,在 4 个养护龄期下,使用不同再生骨料和 6 种替代率 (r) 的两组 RAC进行了测试。 [18] 本文报告了一项关于采用再生砖骨料 (RBA) 作为相变材料 (PCM) 载体制成的可持续水泥复合材料的实验结果。 [19]
recycled brick powder 再生砖粉
The objective of this paper is to evaluate the geotechnical performance of a clay soil of high plasticity added with recycled brick powder (RBP) and recycled gypsum powder (RGP), both obtained in “waste” condition. [1] In this study, in order to study the freeze-thaw resistance of wet-mix plaster mortar after replacing artificial sand (AS) with full-component recycled sand (FCRS) and recycled brick powder (RBP) instead of fly ash (FA), ratio of binding material to fine aggregate (RBMFA) (1:5, 1:6 and 1:7), types of fine aggregate (TFA) (AS and FCRS) and kinds of mineral admixture (KMA) (FA and RBP) were considered as research variables. [2] In this context, grinding brick waste into recycled brick powder (RBP) and using it instead of cement to produce sustainable construction materials is considered a feasible method. [3] The relationship between recycled brick powder content and cement mortar strength is almost linear to 20% limit. [4] The content of recycled brick powder (RBP) in a hybrid recycled powder (HRP) was an important factor. [5] The basic properties of the fly ash, recycled brick powder and recycled concrete powder, compared the recycled brick powder and recycled concrete powder instead of fly ash in concrete preparation, influence on the working performance and mechanical properties; and through the modifier to improve the concrete slump loss is too large, analyzes the mechanism of change influence of modifiers on mechanical properties of concrete. [6]本文的目的是评估添加了再生砖粉 (RBP) 和再生石膏粉 (RGP) 的高塑性粘土的岩土工程性能,这两种材料都是在“废弃”条件下获得的。 [1] 在本研究中,为了研究用全组分再生砂(FCRS)和再生砖粉(RBP)代替粉煤灰(FA)代替人造砂(AS)后湿拌抹灰砂浆的抗冻融性,结合材料与细骨料的比例 (RBMFA) (1:5, 1:6 和 1:7), 细骨料 (TFA) 的类型 (AS 和 FCRS) 和矿物掺合料 (KMA) 的种类 (FA 和 RBP)视为研究变量。 [2] 在这种情况下,将废砖磨成再生砖粉(RBP)并用它代替水泥生产可持续建筑材料被认为是一种可行的方法。 [3] 再生砖粉含量与水泥砂浆强度之间的关系几乎呈线性关系,达到 20% 的极限。 [4] 混合再生粉末 (HRP) 中再生砖粉 (RBP) 的含量是一个重要因素。 [5] 粉煤灰、再生砖粉和再生混凝土粉的基本性能,比较了再生砖粉和再生混凝土粉代替粉煤灰制备混凝土时对工作性能和力学性能的影响;并通过改性剂改善混凝土坍落度损失过大,分析改性剂变化对混凝土力学性能影响的机理。 [6]
