钢筋混凝土结构耐久性分析及改善措施

Concrete Structure Durability Analysis and Promoting Measures

混凝土的裂缝、剥落、冻胀、钢筋的锈蚀等病害,严重影响结构的耐久性,甚至于危及到结构的使用安全。本文介绍了影响混凝土结构耐久性的病害的表现形式、形成的机理。分析了影响结构耐久性的因素,并从设计——材料——施工等环节,提出了提高混凝土结构耐久性的措施。

Crack,shelling off,frost heaving,and corrosion of steel bars is the disease which affects the durability and service safety of the structure.This article introduces the expressions and the formation mechanism of the disease which affects the structure durability;the factors of structure durability are analyzed.The measures which promote the concrete structure durability are put forward from design,material and construction.
