This study investigated the engineering properties of diatomite replaced cement to make cement mortar. The test variables include water/cement ratio (W/C) of 0.4, 0.5 and 0.6, and the substitution amount of diatomite is 0%, 5%, 10% and 20%. The curing age is 3, 7,28,and 56 days,and the high temperatures are 30...
