摘　　要：混凝土的各项性能都是基于胶凝材料的水化而形成的。科技人员的目标是提高水化产物性能和对这一过程进行控制。水化过程中,胶凝材料从凝聚态的固溶体,经过水的作用,形成絮凝体的水化产物,经历了溶解、扩散、化合反应、结晶、絮凝和结构形成等多个物理化学过程。这些过程中,胶凝材料在水的作用下组成粒子发生变化,形成新的粒子,在自发状态下重排,形成了新的产物结构。The properties of concrete are based on the hydration of cementitious materials. The goal of scientists and technicians is to improve the performance of hydration products and obtain control of this process. In the hydration process, the cementitious material forms the hydration product of the floc from the condensed solid solution through the action of water, which has experienced many physicochemical processes, including dissolution, diffusion, chemical reaction, crystallization, flocculation and structure. In these processes, the constituent particles of cementitious materials change under the action of water, form new particles, rearrange in the spontaneous state, and form a new product structure.
