提高混凝土耐久性的技术措施

On Technical Measures to Raise the Durability of Concrete

混凝土是现代工程建设的最主要的材料,混凝土的耐久性是工程设计最重要的技术指标,提高混凝土耐久性就是要通过技术措施提高混凝土抗裂、抗渗、抗碳化、抗碱反应能力,使混凝土工程满足使用功能和要求。尤其是水工混凝土对于抗渗、抗裂以及防侵蚀的要求更高,文中以水工混凝土为例简要介绍提高混凝土耐久性的主要技术措施。

The concrete is the main meterail in modern engineering construction.The durability of the concrete is the most important technical index in the engineering design.In order to raise the durability of concrete,the ability of concrete to resist the cracking,seeping,carbonating and the alkali reacting must be raised by technical measures,so that to meet the use function and demand.Especially the demands on resisting crack and seepage for the hydraulic concrete are higher.In this paper,taking the hydraulic concrete as an example,the main technical measures to raise concrete's durability are introduced.
