硫酸盐侵蚀混凝土力学性能及侵蚀产物研究进展
|
摘要
大量新建混凝土建筑物和构筑物的出现使得混凝土耐久性问题受到格外关注,其中硫酸盐侵蚀是引起混凝土结构过早破坏的四大主因之一。针对侵蚀产物浓度研究成为耐久性研究新的技术领域,本文系统总结了国内外关于硫酸盐侵蚀后混凝土的力学性能劣化规律及钙矾石、二水石膏等膨胀性产物的定性、定量分析研究现状,指出了研究中存在的问题。并且针对分析中发现的不足,为今后的研究提出了建议。
The emergence of a large number of new concrete buildings and structures has caused special attention to the durability of concrete. Among them, sulfate erosion is one of the four main causes of premature failure of concrete structure, and the concentration of erosion products becomes a new idea for durability research. Here, the deterioration law of mechanical properties of concrete after sulfate erosion and the research status of qualitative and quantitative analysis of expansion products such as ettringite and gypsum are systematically summarized. The existing problems are pointed out. In view of the deficiencies found in the analysis, some suggestions are proposed for future research.
