山东省《混凝土结构耐久性设计规程》内容简介

Introduction of design regulation for durability of concrete structures in Shandong province

针对山东省的地理气候及环境特点,编制了工程建设标准《混凝土结构耐久性设计规程》.将环境作用分为混凝土碳化引起钢筋锈蚀、氯离子引起钢筋锈蚀、冻融对混凝土侵蚀、化学腐蚀对混凝土侵蚀共四种环境类别,每种环境类别又进行了环境条件分区及示例.规定了混凝土结构耐久性设计的原则、内容、结构构造和材料选用基本要求、混凝土保护层厚度设计值、裂缝宽度限值等,并给出了防腐蚀附加措施及试验方法.

According to the geography climate in Shandong province, an engineering construction standard ＂Design Regulation for Durability of Concrete Structures＂ is compiled in Shandong province. In the regulation, the environment is classified as four types： corrosion induced by carbonation, corrosion induced by chloride, freeze-thaw attack, and chemical attack. More over, examples and forward zoning are supplied under each type. The regulation specifies the principles, contents, detailing and material requirements, design value of concrete cover depth, crack width limiting, additional anti-corrosion measures and test methods.
