摘    要:为全面系统地研究混凝土在应力与腐蚀介质耦合作用下的环境响应,利用专门设计的应力腐蚀加载试验装置,分析了高性能混凝土在三分点加荷与腐蚀溶液同时作用下的性能衰减规律,及各试验结果对应力腐蚀评价指标的敏感性。结果表明,在一定的试验周期内,受应力腐蚀高性能混凝土的抗折强度损失率在10%以上,而抗压强度及质量基本不变,因此在评价其应力腐蚀性能指标方面以抗折强度损失率最为敏感。

关 键 词:路面工程  高性能混凝土  应力腐蚀  评价指标

Abstract:The stress-corrosion damage of concrete is the coupled action result of stress and corrosion medium, and its study is in exploratory stage. With the loading test equipment of stress-corrosion, the attenuation discipline of high-property-concrete's performance under the action of three-points loading and corrosion solution was studied, the sensitivity of testing results to the stress-corrosion-evaluation indices was analyzed. The results indicate that the loss rate of high-property-concrete's bending strength under the action of stress-corrosion is over 10%, its compression strength and quality usually have no change, the bending strength loss rate is most sensitive to the evaluation indices of concrete's stress-corrosion performance. 8 tabs, 2 figs, 7 refs.
Keywords:pavement engineering  high-property-concrete  stress-corrosion  evaluation indices
