通过单轴重复荷载的实验研究发现:砂浆受硫酸盐侵蚀后,不同侵蚀时的弹模随每一个滞环循中的峰值应变的发展有一定的特征;并将实验数据编制成图,从图中进一步分析和探讨,总结出其发展的三个阶段。
Through the uniaxial repeated loading experiment, it is found that there are some characteristics of the elastic modulus of the mortar under the erosion of sulfate attack with the development of the peak strain in every hysteresis loop. The experimental data are compiled into graphs, In further analysis and discussion, summed up the three stages of its development.
