High-crack-resistance wear-resistant cement and preparation method thereof
The invention discloses high-crack-resistance wear-resistant cement and a preparation method thereof. The high-crack-resistance wear-resistant cement is prepared from the following raw materials in parts by weight: 55 to 75 parts of coal gangue cement clinker, 5 to 10 parts of aluminum sulfate slag, 10 to 15 parts of admixture and 0.05 to 0.15 part of grinding aid, the high-anti-cracking wear-resistant cement is prepared by the following steps: uniformly mixing coal gangue cement clinker, aluminum sulfate slag, an admixture and a grinding aid to prepare the high-anti-cracking wear-resistant cement, the admixture and the grinding aid are introduced into the formula, the grinding aid is prepared from ethylene glycol, propylene glycol and rice hull ash, the rice hull ash can be jointly adsorbed on the surfaces of cement particles along with the ethylene glycol and the propylene glycol, and the grinding aiding effect of the grinding aid is further improved. And the basalt fiber provides anti-cracking performance for the cement.
本发明公开了一种高防裂耐磨水泥及其制备方法，包括如下重量份原料：55‑75份煤矸石水泥熟料，5‑10份硫酸铝渣，10‑15份掺合料，0.05‑0.15份助磨剂；该高防裂耐磨水泥包括如下步骤制成：将煤矸石水泥熟料、硫酸铝渣、掺合料和助磨剂混合均匀，制得高防裂耐磨水泥；配方中引入了掺合料和助磨剂，其中助磨剂由乙二醇、丙二醇和稻壳灰制成，稻壳灰可随乙二醇和丙二醇共同吸附在水泥颗粒的表面，进一步提高助磨剂的助磨效果，本发明还制备出一种掺合料，引入了改性玄武岩纤维，通过玄武岩纤维本身为水泥提供抗开裂性能。
