混凝土受硫酸盐腐蚀的试验方法

A Test Method about Sulfate Attacking on Concrete

在归纳室内加速试验方法的基础上,设计了一种新的模拟现场条件的硫酸盐侵蚀混凝土的试验方法:采用强度等级为C20,C40,C60,C80的混凝土和高、中、低3种硫酸盐溶液浓度,以及接近自然状态的干湿循环方式,确定了宏观测试指标和测定试样中硫酸盐侵蚀深度和硫酸根离子分布及量化分析的方法,为该方面的研究提供了一条新途径.

Based on the summary of the laboratory accelerate tests,a new test method is designed for simulating the field conditions.The strength grade of concrete is from C20,C40,C60,C80,three typical concentrations of low,medium and high of sulfate solution are adopted,wetting and drying cyclice modes closing to natural state is established.the macroscopic test indexes,the method of measuring the corrosion depth and sulfate-ion concentration,and the quantification analysis,are defined,this provides a new method for ...
