摘要:热力学和动力学可用于水泥基材料尤其是水泥浆体设计中。热力学的应用便于选择水泥浆体需要的化学组分,使得该材料具有宏观孔隙的特
殊相组合,而动力学的应用,一方面可以提高早期水泥水化过程中的水化率,另一方面可以调节该材料的宏观孔隙的分布。对于含有水化硅酸钙的水
泥浆体,控制晶核形成和生长的速率有助于改变细观孔隙的分布。因此,应用热力学和动力学研究水泥基材料的物理化学特性,可以大大改善这些材

Abstract: Thermodynamics and ics applied to cement-based materials and especially to cement paste are very powerful in order
to design better engineered and more sustainable construction materials. Indeed thermodynamics enables to choose the required
position in order to reach specific phase assemblages with a defined macro-porosity. On the other hand, controlling the
ics is essential first to reach high percentage of reaction during cement hydration at short ages, and second, to tu
