The influence of solid waste on the performance of ready-mixed mortar was studied through orthogonal experiments,and the optimal composition ratio scheme was determined by combining cost analysis.The test results show that when ceramic waste replaces 30％cement,tailings sand replaces 60％river sand,and is mixed with 2％calcium chloride,0.1％HPMC and 0.04％8681 rubber powder,the preparation cost of M5 mortar is the lowest,which can save 36.70 yuan per ton of mortar,and the reduction rate of raw material cost reaches 25.36％.
