新型混凝土外加剂抗渗性能研究

针对铁路隧道结构防水问题，本文引进一种新型混凝土外加剂。通过抗压强度、渗透高度比、盐雾试验和6h库仑电量法测试，结果表明该外加剂不仅能提高混凝土的强度，而且在混凝土抗渗透性方面有明显的效果，可以有效地解决隧道混凝土结构渗漏水问题。

The research of a new type concrete admixture with anti-leakage

Aiming at railway tunnel structure waterproof, this paper introduces a new type concrete admixture .Through compression strength, permeability highness ratio, neutral salt spray test and chloride ion penetration rote test,the research result indicates that it not only enhances concrete strength .but also have superiority effect on concrete anti-leakage,and solves leakage problem about tunnel concrete structure effectively.
