Hardening Concrete(硬化混凝土)研究综述
Hardening Concrete 硬化混凝土 - This research study examined an IoT-based concrete curing control system based on sensor technologies invented for monitoring and controlling the moisture content of hardening concrete to the levels appropriate for good quality hardened concrete. [1] Based on the fact that the absolute leader in the use of reinforced concrete as the main building material, it is important and necessary to observe all the quality characteristics of this material both at the stage of laying the concrete mixture in the formwork, and in the process of maintaining the hardening concrete until the termination of heat-and-humidity care for it. [2] The proposed method consists in a preliminary calculation of temperature fields in hardening concrete. [3] Moreover, the model is also shown to provide excellent agreement with the work of Savija and Schlangen, who simulated the transient thermal response of hardening concrete using the commercial finite element package FEMMASSE. [4] This paper first introduces a multi-field (hydro–thermo–hygro–constraint) coupling model with the hydration degree of cementitious materials as the basic state parameter to estimate the shrinkage cracking risk of hardening concrete under coupling effects. [5] For each of these cases, the analysis of exergetic flows was carried out, the structure of the exergy of the concrete mixture and the hardening concrete was determined. [6] The kinetics of heat transfer in hardening concrete is a key issue in engineering practice for erecting massive concrete structures. [7] Shrinkage deformation of hardening concrete, indicators of fracture toughness, frost resistance, and thermal conductivity were determined during the experimental works. [8] The result is agglomerations of hardening concrete, that might be utilised for aggregate. [9] For the purpose of delving deep into the preparation process and early working performance of inorganic cementitious composite material, and analyzing its application prospect in pavement emergency repair, the slag, fly ash and silica fume are used as solid cementitious materials, and sodium hydroxide and sodium silicate are used as alkali-activators to prepare inorganic polymer-based fast-hardening concrete (IPFC). [10] In article features of influence of heat exchange of the hardening concrete of designs and environment taking into account ensuring crack resistance of concrete are considered. [11] The effects of abraded fine particle content on the failure process of quick-hardening concrete were investigated using digital image correlation (DIC) analysis during the testing of modeled cored aggregate concretes (MCACs). [12] The paper presents the results of own thermally stressed state of hardening concrete when determining the permissible temperature gradient in it, which made it possible to speed up the process of building the object while observing the necessary properties. [13] The paper discusses the use of different methods of the hardening concrete’s temperature regime, depending on the boundary conditions specified in the design and construction of the object. [14]这项研究检查了基于物联网的混凝土固化控制系统，该系统基于传感器技术，用于监测和控制硬化混凝土的含水量，使其达到适合优质硬化混凝土的水平。 [1] 基于使用钢筋混凝土作为主要建筑材料的绝对领导者这一事实，无论是在模板中铺设混凝土混合物的阶段，还是在保持硬化混凝土的过程，直到终止对它的湿热护理。 [2] 所提出的方法在于对硬化混凝土中的温度场进行初步计算。 [3] 此外，该模型还显示出与 Savija 和 Schlangen 的工作非常一致，他们使用商业有限元包 FEMMASSE 模拟了硬化混凝土的瞬态热响应。 [4] 本文首先介绍了一种以胶凝材料水化度为基本状态参数的多场（水-热-湿-约束）耦合模型来估计耦合作用下硬化混凝土的收缩开裂风险。 [5] 对于这些案例中的每一个，都进行了火用流动分析，确定了混凝土混合物和硬化混凝土的火用结构。 [6] 硬化混凝土中的传热动力学是建造大体积混凝土结构的工程实践中的一个关键问题。 [7] 在试验过程中确定了硬化混凝土的收缩变形、断裂韧性、抗冻性和导热系数等指标。 [8] 结果是硬化混凝土的团聚，可用于骨料。 [9] 为深入研究无机胶凝复合材料的制备工艺和早期工作性能，分析其在路面应急修复中的应用前景，以矿渣、粉煤灰、硅灰为固体胶凝材料，氢氧化钠、钠硅酸盐被用作碱活化剂来制备无机聚合物基快硬混凝土（IPFC）。 [10] 在文章中考虑了考虑到确保混凝土的抗裂性的设计和环境的硬化混凝土的热交换影响的特征。 [11] 在模拟芯骨料混凝土 (MCAC) 的测试过程中，使用数字图像相关 (DIC) 分析研究了磨损细颗粒含量对快硬混凝土破坏过程的影响。 [12] 本文介绍了硬化混凝土在确定其允许温度梯度时自身的热应力状态的结果，这使得在观察必要特性的同时加快建造对象的过程成为可能。 [13] 本文讨论了硬化混凝土温度状态的不同方法的使用，具体取决于对象的设计和构造中指定的边界条件。 [14]

In addition, measured thermal conductivity and specific heat capacity of IBA were combined with calculated thermal output and used as input to a model originally developed for accessing temperature development in hardening concrete structures. [1] The proposed method of calculating considers a mathematical model of the temperature field in a hardening concrete structure of any shape with different conditions on the heat exchange surfaces and can be applied in various ways of heat treatment of concrete. [2]此外，测得的 IBA 的热导率和比热容与计算的热输出相结合，并用作最初开发的模型的输入，该模型最初是为了解硬化混凝土结构的温度发展而开发的。 [1] 所提出的计算方法考虑了任意形状的硬化混凝土结构中温度场的数学模型，在不同的换热表面条件下，可以应用于混凝土的各种热处理方式。 [2]
