提高水泥混凝土抗渗性的研究进展及存在的问题

Advances and open questions in researches to improve concrete impermeability.

混凝土的抗渗性直接关系着混凝土的耐久性。提高混凝土抗渗性通常有两种技术路线,一种是通过第三介质隔断渗透物与混凝土的接触来提高混凝土的抗渗性,另一种是通过提高混凝土自身的密实性来提高混凝土的抗渗性。本文分别就各种提高混凝土抗渗性的技术及其进展进行了探讨。

the anti-penetrating performance of concrete are directly performance. To improve the anti-penetrating performance of concrete, there insulate concrete from penetrating by third mediums, the other is to promote This paper discussed the technologies and developments on the anti-penetrating related to the durability are two ways： one is to the impaction of concrete. performance of concrete.
