酸介质和冻融循环协同作用下混凝土性能研究

由于各因素的相互影响,根据单因素的研究结果分析实际工程混凝土耐久性得出的结论的可靠性不足,此次试验进行了酸性溶液和低温冻融环境共同作用下的混凝土耐久性能研究,结果表明,经酸性溶液侵蚀和不同冻融循环次数处理过的混凝土,应力应变曲线趋于扁平,抗压性能劣化、峰值应力变低、弹性模量下降。

Simulated groundwater environment and cryogenic freezing and thawing effect on the performance of concrete

Due to the interaction of various factors,according to the results of single factor deficiency to analyze the actual durability of concrete conclusions reliability. Carried out under acidic solution of concrete durability and low temperature freeze-thaw environment interaction energy re-search. The results showed that the acidic solution had eroded concrete,with the increase in the number of freeze-thaw cycles,the stress-strain curve tends to be flat,compression performance degradation,low peak stress,peak strain increases,the elastic modulus decreased.
