Retarding cement grinding aid doped with tartaric acid byproduct and using method
The invention belongs to the technical field of building materials, and particularly relates to a retarding cement grinding aid doped with a tartaric acid byproduct and a using method. Raw materials used by a product of the invention comprise the tartaric acid byproduct, sodium polyphosphate, glycerol, calcium lignosulphonate, and water. Due to good system stability of the product of the invention, cement grinding efficiency can be obviously improved, cement hydration is delayed, and physical properties such as ground cement particle size distribution and cement strength are improved. According to the product of the invention, the tartaric acid byproduct can be sufficiently utilized, and an added value of tartaric acid waste liquid is improved. The product is simple in preparation method and low in production costs, and has good economic benefit and social benefit.
