混凝土的耐久性

本文对混凝土耐久性研究成果作了简要回顾与论述，对混凝土耐久性的检测内容与方法进行了思考，认为研究混凝土的耐久性应同时兼顾其体积稳定性和均质性，其检测方法的研究似乎比混凝土耐久性本身的研究更为迫切，系统地、动态地研究服役中混凝土的耐久性，能够将科学研究与工程实际较好地融合；阐述了高性能混凝土的普通性和特殊性，提出了高性能混凝土范畴模型及其配制原则，认为同强度等级的混凝土并不意味着相同的耐久性。

Durability of concrete

The research achievement of concrete durability is reviewed briefiy in this paper.The content and method about concrete durability are considered.The volume stability and homogeneity are considered at the same time during studing concrete durability.It is considered that research of measuring method is more important than that of concrete durability.Studied systematically durability of concrete in used can well connect with actual engineering.Univerality and speciality of high performance concrete are expounded.The category model and mixing principle of high performance.concrete is put forward.The research result shows that the serve life of the same strength grade concrete is different.
