Environment-friendly cement and preparation method thereof
The invention discloses environment-friendly cement and a preparation method thereof. The environment-friendly cement is prepared from limestone, coal ash, fluorgypsum, kaolin, industrial waste residues, modified natural rubber, coal gangue, vanadium slag, a reinforcing agent, an anti-permeability agent and water, and the modified natural rubber, the limestone and the coal ash are added into the prepared cement for effective filling; the strength and durability of cement are improved, in addition, the kaolin can change the grain composition of the cement, improve the coarse grain content of the cement, enhance the skeleton effect and further improve the strength and durability of the cement, so that the cement has a wide application prospect, and meanwhile, the reinforcing agent is added in the cement preparation process; the reinforcing agent reduces the viscosity of the cement material and promotes the dispersion of the particles by adjusting the fluidity of the cement material and the surface electrical properties of the particles, so that the flowability of the cement material is improved, the initial setting time in the cement preparation process is remarkably prolonged, and the later compressive/flexural strength is also remarkably improved.
本发明公开了一种环保水泥及其制备方法，包括以下原料：石灰石、粉煤灰、氟石膏、高岭土、工业废渣，改性天然橡胶、煤矸石，钒渣、增强剂、抗渗剂和水，本发明制备的水泥中加入改性天然橡胶、石灰石、粉煤灰进行有效的填充，提高了水泥的强度和耐久性，另外高岭土能改变水泥的颗粒级配，提高水泥的粗颗粒含量，增强骨架作用，进一步提高水泥的强度及耐久性，具有广泛应用前景，同时在水泥制备过程中加入增强剂，增强剂通过调节水泥物料的流度和颗粒的表面电性，降低水泥物料的黏度，促进颗粒的分散，从而提高水泥物料的可流动性，使水泥制备过程中初凝时间显著延长，后期抗压/抗折强度也明显提高。
