Cement grinding aid
The invention discloses a cement grinding aid which comprises the following components in percentage by mass: 4-10% of an alcohol amine compound, 10-15% of polyol, 3-10% of a retarder and the balance of water. According to the prepared cement grinding aid, the 28-day strength of cement prepared from mine limestone with excessive impurities can reach 59 MPa, and compared with the 28-day strength 50 MPa before the cement grinding aid, the cement strength of the cement grinding aid is improved by 18% and is higher than the national lowest standard 52.5 MPa. The mixing amount of the cement grinding aid is low, the quality of cement prepared from mine limestone with excessive impurities is improved, the utilization rate of resources is increased, and the production cost is greatly reduced.
本发明公开了一种水泥助磨剂，包括以下质量百分数的醇胺类化合物4‑10％、多元醇10‑15％、缓凝剂3‑10％、余量的水。所制备的水泥助磨剂可以使杂质过多的矿山石灰石制备成的水泥28天强度高达59MPa，相比于水泥助磨剂前的28天强度50MPa，其水泥强度提高了18％，且高于国家最低标准52.5MPa。该水泥助磨剂的掺量低，且提高了杂质过多的矿山石灰石制备成水泥的品质，提高了资源的利用率，大大降低生产成本。
