Energy-saving cement and preparation method thereof
The invention discloses energy-saving cement and a preparation method thereof, which belong to the technical field of cement production. The energy-saving cement comprises cement clinker and an admixture, wherein the cement clinker is mainly prepared from the following raw materials in parts by weight: 42-45 parts of power plant fly ash, 8-9.5 parts of bauxite, 80-98 parts of limestone, 0.3-2 parts of gypsum and 1.5-2.5 parts of iron ore. The preparation method of the energy-saving cement comprises the following steps of: 1) mixing and grinding the raw materials of the cement clinker to prepare a raw material, preheating and decomposing the raw material, sintering at 1050-1250 DEG C for 20-30 minutes, and cooling to prepare the cement clinker, and (2) mixing and grinding the cement clinkerprepared in the step (1) and the admixture to obtain the energy-saving cement. The raw materials of the cement clinker of the energy-saving cement cooperate with each other, so that the sintering temperature is reduced, and the energy is saved.
本发明公开了一种节能型水泥及其制备方法，属于水泥生产技术领域。本发明的节能型水泥，包括水泥熟料和混合材，所述水泥熟料主要由如下重量份数的原料制成：电厂粉煤灰42‑45份、铝矾土8‑9.5份、石灰石80‑98份、石膏0.3‑2份、铁矿石1.5‑2.5份。本发明的节能型水泥的制备方法包括如下步骤：1）将水泥熟料的原料混合粉磨，制得生料，然后将生料进行预热、分解，然后在1050‑1250℃下烧结20‑30min，冷却，制得水泥熟料；2）将步骤1）制得的水泥熟料与混合材混合粉磨，即得。本发明的节能型水泥的水泥熟料的各原料相互协同，降低了烧结温度，节约了能源。
