摘要

据报道，近年来，现代波特兰水泥熟料的化学/矿物组成发生了很大的变化，由此制成的水泥可能导致混凝土耐久性问题，即使这种水泥通过了适用的规格。举例说明了熟料中含硫化合物对延迟磨辉石形成的混凝土劣化的影响。本文根据现有的实验室数据和现场经验，对相关问题进行了简要评价。

Sulfates in Cement Clinker and Their Effect on Concrete Durability

It has been reported that the chemical/mineralogical composition of modern portland-cement clinkers has changed in recent years to such a degree that cements made from them may lead to concrete durability problems even if such cement passed the applicable specifications. The effect of sulfur compounds in clinker on concrete deterioration due to delayed attringite formation is cited as an example. In this paper, the relevant issues are briefly evaluated in light of available laboratory data and field experience.
