混凝土耐久性若干问题的讨论

耐久性不仅是涉及建筑材料的课题，而且涉及建设可持续发展的国土环境的目标。混凝土的久性涉及许多方面，如保持低渗透性、快速试验方法的正确评价、从强度设计向性能设计转化、劣化与基本组分的关系、路面与桥面板的使用寿命等。

A STUDY INTO SOME PROBLEMS OF CONCRETE'S DURABILITY

The problems of concrete durability not only affect many properties of building materials,but also influence those goals of successive developments of a national enviroment.The concrete durability affects widely in many fields namely:1,preservation of a low permeability 2,proper appraisal of a continual quick experiment method 3,transfer from strength design into property design 4,relationship between poor quality and basic pottion and 5,service life of road pavement and bridge pavement.
