Composite cement with few silicate clinker components, and preparation method thereof
The invention belongs to the technical field of cementing materials, and discloses a composite cement with few silicate clinker components, and a preparation method thereof. The composite cement with few silicate clinker components comprises the following preparation raw materials: silicate cement clinker, gypsum, slag powder, fly ash, limestone powder and aluminosilicate mineral powder; the use amount of silicate clinker in the obtained composite cement is small, the clinker component can be as low as about 30%, the total doping amount of mixed material components such as slag, fly ash, volcanic ash, industrial solid waste and limestone can be as high as about 70%, energy and limestone resources can be saved, and CO2 emission is reduced; meanwhile, a large amount of industrial solid wastes such as slag, fly ash and furnace bottom slag can be consumed, the environment is protected, and the cement production cost is reduced; and the preparation method is simple, easy to operate and implement and convenient for realizing industrial application.
本发明属于胶凝材料技术领域，公开了一种少硅酸盐熟料组分复合水泥及其制备方法，该少硅酸盐熟料组分复合水泥包括以下制备原料：硅酸盐水泥熟料及石膏、矿渣粉、粉煤灰、石灰石粉、硅铝酸盐矿物粉；所得复合水泥中硅酸盐熟料用量少，熟料组分可以低达30％左右，矿渣、粉煤灰、火山灰质、工业固废、石灰石等混合材组分掺加总量可以高达70％左右，可节约能源和石灰石资源，减少CO2排放；同时可大量消纳矿渣、粉煤灰、炉底渣等工业固体废弃物，保护环境，降低水泥生产成本；其制备方法简单，易操作实施，便于实现工业化应用。
