摘要: 再生集料中含有未水化的水泥颗粒，这使得再生集料在遇水时会表现出一定的凝胶活性。此外，再生集料混凝土具有密度小、孔隙率高等特点，在胶凝材料水化硬化过程中，吸附在再生集料孔隙中的水分还会起到内养护的作用，进而会对混凝土界面过渡区结构产生影响。基于此，本章对再生集料对混凝土力学行为的影响进行了深入研究，揭示固体废弃物作集料的界面过渡区效应对混凝土力学性能的影响规律。
Abstract: Recycled aggregate contains unhydrated cement particles, which can make it exhibit gel activity when encountering water. In addition, recycled aggregate concrete has the characteristics of small density and high porosity. In the process of hydration, the moisture adsorbed in the pore of recycled aggregate will also play a role of internal curing, which will affect the structure of the ITZ. Based on this, this paper will study the influence of recycled aggregate on the mechanical behavior of concrete, and reveal the influence regularity on the mechanical properties of concrete.
