The invention discloses environment-friendly cement and a preparation method thereof. The environment-friendly cement comprises the following components in percentage by mass: 75%-80% of limestone, 8%-14% of high-iron sulfate slag, 1%-1.5% of mineral powder, 0.5%-1.5% of polyacrylamide, 1.5%-2% of an additive and 0.5%-1% of a mineralizer. The polyacrylamide is added into the cement and is mixed with the cement mortar, so that the bonding strength and the flexibility of the cement mortar can be effectively improved, the adhesive force is improved, the cement mortar is leakage-proof, the cement mortar has good obdurability and has a good waterproof effect, the polyacrylamide can enhance the leakage-proof and waterproof performance of the mortar, and also has anti-aging, non-toxic and safe performance, and by doping a proper amount of iron ore powder, the fluidity of the concrete can be improved, the hydration heat of cement can be reduced, the impermeability of the concrete can be improved, the later strength can be improved, the internal structure of the concrete can be improved, and the impermeability and corrosion resistance can be improved.
本发明公开了一种环保型水泥及其制备方法，包括按质量分数计算包括石灰石(75％～80％)、高铁硫酸渣(8％～14％)、矿粉(1％～1.5％)、聚丙烯酰胺(0.5％～1.5％)、添加剂(1.5％～2％)和矿化剂(0.5％～1％)。本发明通过往水泥内加入聚丙烯酰胺，聚丙烯酰胺与水泥砂浆混合，可以有效提高水泥砂浆的粘结强度和柔韧性，提高粘贴力，防渗漏，能使其具有很好的强韧性，并使之起到很好的防水作用，聚丙烯酰胺能增强砂浆的抗渗漏防水性能，还具有抗老化性、无毒、安全的性能，掺入适量铁矿粉,可改善混凝土流动度,降低水泥水化热,提高混凝土抗渗能力,提高后期强度、改善混凝土的内部结构,提高抗渗和抗腐蚀能力。
