Mining high-strength composite mortar material and preparation method thereof
The invention provides a mining high-strength composite mortar material. The material comprises the following raw materials in percentage by mass: 40%-70% of stone powder, 10%-40% of clinker, 3%-10% of an accelerator, 5%-10% of cellulose, 2%-10% of aluminum sulfate and 2%-10% of a water reducing agent. A preparation method of the mining high-strength composite mortar material comprises the following steps: 1, preparing the stone powder, the clinker, the accelerator, the cellulose, the aluminum sulfate and the water reducing agent in a desired ratio; 2, mixing the clinker with the cellulose toobtain a mixed material A; 3, mixing the stone powder and the aluminum sulfate to obtain a mixed material B; 4, mixing 1/2 of the mixture A and 1/2 of the mixture B with the accelerator and the waterreducing agent to obtain a mixture C, and mixing the rest of the mixture A and the rest of the mixture B to obtain a mixture D; 5, sequentially adding the mixture C and the mixture D into a stirring machine, and conducting sufficient stirring at a normal temperature for 12-16 min, wherein a stirring speed is 80-100 r/min; and 6, after stirring is completed, packaging a material obtained in the step e to obtain a finished product.
本发明提供了一种矿用高强度复合砂浆材料，由以下质量百分比的原料组成：石粉40％‑70％、熟料10％‑40％、速凝剂3％—10％、纤维素5％—10％、硫酸铝2％—10％、减水剂2％—10％，该矿用高强度复合砂浆材料的制备方法如下：第一，准备相应配比的石粉、熟料、速凝剂、纤维素、硫酸铝和减水剂；第二，将熟料和纤维素混合得到混合物料A；第三，将石粉和硫酸铝混合得到混合物料B；第四，将1/2所述混合料A和1/2所述混合料B与所述速凝剂、所述减水剂混合，得到混合料C，将剩余1/2所述混合料A和1/2所述混合料B混合，得到混合料D；第五，在搅拌机中依次加入混合料C和混合料D，常温下充分搅拌，搅拌时间12‑16min，搅拌速度为80‑100r/min；第六，搅拌完成后，将步骤e所得的物料进行打包即可得到成品。
