钢筋砼的碳化及其防治

本文分析了砼碳化产生的机理以及影响碳化的因素,砼的碳化深度与施工质量水灰比、保护层厚度、骨料粒径、使用环境条件等等因素有关,砼碳化深受随着水灰比的增大而增加。最后提出了砼碳化的预防及治理措施。

CARBONIZATION AND PREVENTION OF REINFORCED CONCRETE

This paper analyzes the mechanism and influence factor of concrete carbonization. The depth of concrete carbonization has much to do with construction quality,water-ce-ment ratio,the thickness of protection layer,the size of aggregate,environmental condi-tions and so on,The depth of carbonization increases with increasing water-cement ratio. The measures of prevention and treatment of concrete carbonization has been presented as the end of the paper.
