Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that cement grinding aids can effectively improve the grinding efficiency of cement particles, but the produced cement particles still have uneven particle sizes, resulting in insufficient hydration reactions and hydration reactions. The rate is not high, resulting in low early strength of cement products

Abstract

The invention relates to the technical field of cement aids, and particularly discloses a cement grinding aid and high-early-strength cement using the same. The cement grinding aid is prepared by stirring and mixing the following components: 10-20 parts of ethylene glycol, 10-20 parts of propylene glycol, 5-10 parts of rice hull ash, 10-20 parts of triethanolamine, 5-10 parts of a refrigerant and 5-15 parts of sodium carbonate. The high-early-strength cement using the cement grinding aid is prepared from the cement grinding aid, and the cement grinding aid can be used for cement production and has the advantage of improving the early strength of cement.

Description

technical field [0001] The application relates to the technical field of cement additives, more specifically, it relates to a cement grinding aid and high early strength cement using the cement grinding aid. Background technique [0002] In the cement production process, it is usually necessary to grind the cement raw materials. During the grinding process, cement grinding aids are added to the cement raw materials. The cement grinding aids can be adsorbed on the surface of cement particles, reducing the attraction between cement particles, and at the same time Improve the fluidity of the grinding, significantly improve the grinding efficiency. [0003] The existing cement grinding aids include liquid and solid, which can significantly increase the output of the mill, improve the product quality, and reduce the power consumption of grinding. [0004] In view of the above-mentioned related technologies, the inventor believes that cement grinding aids can effectively improve ...
