Cement grinding aid and application method thereof in cement with large mixing amount of limestone
The invention discloses a cement grinding aid and an application method of the cement grinding aid in a large-dosage limestone mixed material. The cement grinding aid is prepared from the following components in percentage by mass: 8 to 12 percent of diisoalcohol monoethyl propanolamine, 6 to 10 percent of triethanolamine, 8 to 12 percent of polyhydric alcohol, 4 to 6 percent of sodium carbonate, 12 to 18 percent of liquid sodium thiocyanate and 50 to 56 percent of water. The high-dosage limestone cement is prepared from the following components in percentage by mass: 45 to 55 percent of clinker, 5 to 25 percent of waste limestone, 7 to 14 percent of fly ash, 10 to 14 percent of superfine slag powder, 0 to 14 percent of slag, 3 to 6 percent of desulfurized gypsum and a cement grinding aid, and the addition amount of the cement grinding aid accounts for 0.08 to 0.2 percent of the total mass of the high-dosage limestone cement. According to the cement grinding aid and the large-dosage limestone cement provided by the invention, the occupied area emission of the waste limestone is reduced, the comprehensive utilization rate of the waste limestone is improved, the purposes of reducing the cost, increasing the benefit and protecting the environment are achieved, and the use performance of the cement is improved.
本发明公开了一种水泥助磨剂及其在大掺量石灰石混合材料中的应用方法，该水泥助磨剂包括以下组分及各组分的质量百分数为：二异醇单乙丙醇胺8～12％，三乙醇胺6～10％，多元醇8～12％，碳酸钠4～6％，液体硫氰酸钠12～18％和水50～56％。大掺量石灰石水泥包括以下组分及各组分的质量百分数为：熟料45～55％、石灰石废石5～25％、粉煤灰7～14％、矿渣微粉10～14％、炉渣0～14％、脱硫石膏3～6％和水泥助磨剂，其中，水泥助磨剂的添加量占大掺量石灰石水泥总质量的0.08～0.2％。本发明提出的一种水泥助磨剂及大掺量石灰石水泥，减少了石灰石废石占地排放，提高了石灰石废石综合利用率，实现了降成本增效益、保护环境的目的，并且提高了水泥使用性能。
