Cementing material composition, cementing material as well as preparation method and application of cementing material
The present invention relates to the technical field of building materials, and discloses a cementing material composition, the composition comprises first fly ash, second fly ash, water and Portland cement, the first fly ash and the second fly ash respectively contain CaO, and the CaO content in the first fly ash is less than the CaO content in the second fly ash. According to the cementing material composition, the cementing material prepared by compounding the fly ash has good fluidity and compressive strength, the bleeding rate is small, and the phenomenon that fine particles flow out along with bleeding to pollute the underground environment is avoided; the use amount of fly ash in the cementing material is large, the material cost can be effectively reduced, the cementing material is used in a mine backfill material, the problem of fly ash accumulation can be solved, pollution of fly ash accumulation to atmosphere, water, ecology and other environments is reduced, and meanwhile, the daily management and maintenance cost of fly ash accumulation is reduced; in addition, the cementing material is simple in preparation process and has practicability and industrial feasibility.
本发明涉及建筑材料技术领域,公开了一种胶凝材料组合物,该组合物包括:第一粉煤灰、第二粉煤灰、水和硅酸盐水泥,其中,所述第一粉煤灰和所述第二粉煤灰中各自含有CaO,所述第一粉煤灰中CaO的含量小于所述第二粉煤灰中CaO的含量。本发明的胶凝材料组合物通过复配粉煤灰而制得的胶凝材料兼具良好的流动度和抗压强度,泌水率小,不会产生细颗粒随泌水流出而污染井下环境的现象;本发明的胶凝材料中粉煤灰用量大,可有效解降低材料成本,用于矿井回填材料中,还能够解决粉煤灰堆积问题,减少了粉煤灰堆存对大气、水、生态等环境的污染,同时降低了粉煤灰堆存的日常管理维护的费用;此外,本发明的胶凝材料的制备工艺简单,具有实用性和工业可行性。
