水泥石的耐久性判据

Durability Indexes of Hardened Cement Paste

在一定的环境条件下,混凝土的耐久性主要取决于水泥石的耐久性。基于水泥水化产物的劣化机理,提出了水泥石的3个耐久性判据,并给出了水泥石耐久性设计的3个关键措施。

The long-term performance of concrete mainly depends on the durability of hardened cement paste in a certain service environment. Based on the mechanisms of deterioration of hydration products of cement,three criteria of durability of hardened cement paste were put forward. And the key methods about how to improve the long-term performance of hardened cement past were discussed.
