Environment-friendly high-strength cement and preparation method thereof
The invention discloses environment-friendly high-strength cement and a preparation method thereof, belonging to the technical field of cement manufacturing. The environment-friendly high-strength cement comprises cement clinker and an admixture, wherein the cement clinker is mainly prepared from the following raw materials in parts by weight: 330-350 parts of limestone, 10-12.5 parts of sulfate slag, 50-60 parts of sandstone, 12-16 parts of fly ash and 3-8 parts of copper slag. The preparation method of the environment-friendly high-strength cement comprises the following steps: mixing and grinding the raw materials of the cement clinker to obtain a raw material, preheating and decomposing the raw material, carrying out sintering at 1250-1350 DEG C for 20-25 minutes, and conducting cooling to obtain the cement clinker; and mixing and grinding the cement clinker and the admixture to obtain the cement. According to the environment-friendly high-strength cement, the proportions of all the raw materials in the cement clinker are reasonable, the effects of all the components in the cement clinker can be fully exerted, and the strength of the cement is greatly improved.
本发明公开了一种环保型高强度水泥及其制备方法，属于水泥制造技术领域。本发明的环保型高强度水泥，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：石灰石330‑350份、硫酸渣10‑12.5份、砂岩50‑60份、粉煤灰12‑16份、铜矿渣3‑8份。本发明的环保型高强度水泥的制备方法，包括如下步骤：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1250‑1350℃下烧结20‑25min，冷却，制得水泥熟料；将水泥熟料与混合材混合粉磨，即得。本发明的环保型高强度水泥的水泥熟料中各原料的比例合理，能够充分发挥出水泥熟料中各成分的作用，大大提高了水泥的强度。
