近年来,有关复合胶凝材料的水化硬化机理的研究取得了较大进展。硅酸盐水泥在不同水化阶段的反应机理被广泛深入地探讨,建立了一些水泥基材料水化动力学和浆体微结构形成的预测模型。越来越多的矿物掺合料用于混凝土的制备。本文重点总结了硅酸盐水泥早龄期水化机理、矿物掺合料对硅酸盐水泥水化的影响以及复合胶凝材料反应过程模拟的研究进展。
In recent years, great progress has been made in the research on hydration and hardening mechanism of composite cementitious materials. The reaction mechanism of Portland cement in different hydration stages is discussed extensively and some prediction models of hydration kinetics and microstructure formation of cement-based materials are established. More and more mineral admixtures are used in the preparation of concrete. This article focuses on the early hydration mechanism of Portland cement, the effects of mineral admixtures on the hydration of Portland cement and the research progress on the simulation of reaction process of composite cementitious materials.
