A study on the mechanical properties of mechanism sand mortars subjected to different temperatures
With the reduction of natural sand resources and damages such as farmland destruction, soil erosion caused by excessive sand mining has become worse. The advantage of mechanism sand is more obvious in the use of engineering. Many researchers study about using mechanism sand in engineering applications. But few people have investigated the properties of a mechanism sand mortar that is subjected to different temperatures. Xiaoyan Xu et al.  tested natural sand mortars. Xiaoyong Xu et al. [2, 3] tested high strength concrete. Natural sand replaced by mechanism sand as the main material in mortars is the trend of engineering. Therefore, the change rule of mechanism sand mortars subjected to different temperatures was studied in this paper.
