The invention belongs to the field of buildings, and particularly relates to mortar with the strength grade of M15 and a preparation method of the mortar. The mortar with the strength grade of M15 is prepared from the following raw materials: a solid waste-based cementing material, mortar sand, a water reducing agent and water, wherein the weight ratio of the solid waste-based cementing material to the sand for mortar is 1: 2; the weight ratio of the solid waste-based cementing material to the water reducing agent is 100: 0.8; the weight ratio of the solid waste-based cementing material to the water is 10: 3; the solid waste-based cementing material comprises the following raw materials in percentage by weight: 50-55% of iron-removed high-titanium blast furnace slag, 30-35% of iron-removed steel slag and 10-20% of desulfurized gypsum. According to the technical scheme, the high-titanium metallurgical slag and other solid wastes are fully utilized, the prepared mortar can reach the strength grade M15 standard, and parameters such as the 3d strength, the 7d strength, the 28d strength, the initial setting time and the final setting time of the mortar all meet and exceed relevant standards.
本发明属于建筑领域，具体涉及一种强度等级为M15的砂浆及其制备方法。所述强度等级为M15的砂浆包括如下原料：固废基胶凝材料、砂浆用砂、减水剂和水；其中：所述固废基胶凝材料与所述砂浆用砂的重量比为1:2；所述固废基胶凝材料与所述减水剂的重量比为100:0.8；所述固废基胶凝材料与所述水的重量比为10:3；所述述固废基胶凝材料包括如下重量百分比的原料：除铁高钛高炉渣50～55％、除铁钢渣30～35％、脱硫石膏10～20％。本发明的技术方案充分利用高钛冶金矿渣等固体废弃物，制备得到的砂浆能够达到强度等级为M15的标准，其3d强度、7d强度、28d强度、初凝时间、终凝时间等参数均满足并超过相关标准。
