Cementing material composition, cementing material as well as preparation method and application of cementing material
The invention relates to the technical field of building materials, and discloses a cementitious material composition, a cementitious material, and a preparation method and application of the cementitious material. The cementing material composition comprises aluminate cement, fly ash and water, and the weight ratio of the aluminate cement to the fly ash is (0.4-3): 1. According to the cementing material composition disclosed by the invention, the fly ash and the aluminate cement are matched according to a specific proportion, so that the setting time of slurry can be effectively shortened, and the early strength of the slurry can be improved; the cementing material disclosed by the invention contains a large amount of fly ash, so that the cost of the material can be effectively reduced while relatively high setting speed and relatively high early strength of slurry are ensured, the cementing material is used in a mine backfill material, the problem of fly ash accumulation can be solved, the pollution of fly ash accumulation to the atmosphere, water, ecology and other environments is reduced, and the economic benefit is increased. Meanwhile, the daily management and maintenance cost of coal ash stockpiling 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，公开了胶凝材料组合物、胶凝材料及其制备方法和应用。该胶凝材料组合物包括：铝酸盐水泥、粉煤灰和水，其中，所述铝酸盐水泥与所述粉煤灰的重量比为0.4‑3：1。本发明的胶凝材料组合物通过特定比例的粉煤灰和铝酸盐水泥配合，能够有效缩短浆体的凝结时间，提高浆体的早期强度；本发明的胶凝材料中含有大量的粉煤灰，在保证浆体较快凝结速度和较高早期强度的同时，可有效解降低材料的成本，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。
