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, the hydration mechanism of composite cementitious materials was intensively studied. The mechanisms governing different hydration periods of Portland cement have been widely discussed. Some kinetics models were issued to describe the hydration process of cementitious materials and the formation of paste microstructure. More and more mineral admixture were used during the production of cement and preparation of concrete to improve its workability, mechanical property and durability. In this article, the early hydration mechanisms of the Portland cement, the influence of mineral admixture on the hydration of Portland cement and the simulation of hydration process of composite cementitious materials were reviewed.
