Portland cement
The invention discloses Portland cement, and relates to the technical field of cement production. The Portland cement comprises 80-95% of a wear-resistant anti-cracking special Portland cement clinker, 2-5% of desulfurized gypsum, 2-10% of fly ash, and 1-3% of a green activity activator. The invention also discloses a preparation method of the Portland cement. The preparation method comprises thefollowing steps: drying and ball-milling the desulfurized gypsum; drying the fly ash; mixing and grinding desulfurized gypsum and fly ash; and mixing the powder wear-resistant and crack-resistant special Portland cement clinker, the desulfurized gypsum, the fly ash and the green active excitant in proportion to obtain the Portland cement. Compared with ordinary Portland cement, the Portland cementprepared by the method provided by the invention has the advantages of high breaking strength, good wear resistance, small dry shrinkage, excellent frost resistance, excellent impermeability and excellent impact resistance, has a wider application range, and can be used for construction and repair of roads, airfield runways, hydropower dam spillway tunnels and the like.
本发明公开了一种硅酸盐水泥，涉及水泥生产技术领域，包括80‑95％耐磨抗裂专用硅酸盐水泥熟料、2％‑5％脱硫石膏、2％‑10％粉煤灰、1％‑3％绿色活性激发剂。本发明还公开了一种硅酸盐水泥的制备方法，包括烘干脱硫石膏并球磨；烘干粉煤灰；混合粉磨脱硫石膏和粉煤灰；按比例混合粉末耐磨抗裂专用硅酸盐水泥熟料、脱硫石膏、粉煤灰和绿色活性激发剂制得硅酸盐水泥。本发明方法制得的硅酸盐水泥与普通硅酸盐水泥相比，抗折强度高、耐磨性能好、干缩率小、抗冻性、抗渗和抗冲击性优异，具有更加广泛的应用范围，可用于道路、机场跑道、水电大坝泄洪洞等的修建和修补。
