Powder grinding aid and preparation method thereof
The invention relates to the field of cement grinding aids, and particularly discloses a powder grinding aid and a preparation method thereof. The powder grinding aid is prepared by mixing and drying the following raw materials in parts by weight: 30-50 parts of rice hull ash, 5-10 parts of modified triethanolamine, 3-5 parts of triisopropanolamine, 5-8 parts of water and 2-3 parts of calcium lignosulphonate, wherein the grain size of the rice hull ash is 1-2 microns. The prepared grinding aid has the advantages that the grinding aid performance is good, and the early-stage and late-stage compressive strength of cement can be improved.
