混凝土在浸泡和干湿循环作用下的抗氯盐侵蚀性能
Study on concrete resistance to chloride salt corrosion under full soaking and wet-dry cycling condition
摘要
Abstract
The salt expansion damage characteristics of concrete are studied using test methods of the full soaking and the wet-dry cycling. The research result shows that,after the wet-dry cycling of the chloride solution with different chloride concentrations, the compressive strength of concrete decreases slightly and the flexural strength decreases obviously with the wet-dry cycling age increasing. The microscopic analysis also shows that,the solution of the chloride snow-melting agent with the high chloride concentration has more serious effect on the concrete erosion under the wet-dry cycling condition,and the full soaking has little effect on the strength of concrete.关键词
