High-fluidity solid-waste-based mine water plugging material and preparation method thereof
According to the high-fluidity solid-waste-based mine water plugging material and the preparation method thereof, the high-dosage solid-waste-based mine water plugging material is obtained based on the high-dosage solid-waste-based mine water plugging material composition, the effects of retarding and early strength can be well considered, and meanwhile, the high-fluidity solid-waste-based mine water plugging material has good fluidity. The high-fluidity solid waste-based mine water shutoff material composition provided by the invention comprises the following components in percentage by weight: 4 to 20 percent of aluminate cement, 10 to 80 percent of high-calcium mineral, 10 to 80 percent of fine aggregate, 0.01 to 1 percent of retarder and 0.01 to 1 percent of water reducing agent, and the sum of the weight of the aluminate cement, the high-calcium mineral and the fine aggregate is 100 percent. 0.01-1% of a water reducing agent; wherein the weight content of free calcium oxide in the high-calcium mineral is 2-40%; the weight ratio of the aluminate cement to the high-calcium mineral is 2: (5-16).
本发明提供一种高流动固废基矿井堵水材料及其制备方法，该高掺量固废基矿井堵水材料基于高掺量固废基矿井堵水材料组合物得到，能够很好的兼顾缓凝、早强两方面的效果，同时具有良好的流动度。本发明提供的高流动固废基矿井堵水材料组合物，包括铝酸盐水泥、高钙矿物、细集料、缓凝剂和减水剂，以铝酸盐水泥、高钙矿物、细集料的重量之和为100％计，如下组分的重量百分比为：铝酸盐水泥4‑20％，高钙矿物10‑80％，细集料10‑80％，缓凝剂0.01‑1％，减水剂0.01‑1％；其中，所述高钙矿物中的游离氧化钙重量含量为2‑40％；所述铝酸盐水泥和所述高钙矿物的重量比为2:5‑16。
