Abstract

The invention relates to a method for improving the homogeneity of a cement grinding aid, belonging to the field of cement admixtures. The method mainly comprises the following steps: (I) a water treatment process; and (II) a compounding process for the grinding aid. The water treatment process comprises the following sub-steps: 1, feeding of a purifying agent; 2, sonic treatment; 3, filtration; and 4, thickening treatment of water. Parameters in the above sub-steps are that (1) the weight percentage of the purifying agent is 3 to 10 %; (2) ultrasonic frequency is 20-35 KHZ; (3) the weight percentage of a thickening agent is 2 to 10 %; and (4) time for sonic treatment is 10 to 30 min. The compounding process comprises the following sub-steps: adding water obtained after treatment by the process (I) into a container, dissolving a salt, and carrying out sonic treatment; and successively adding alcohol amine and industrial waste, carrying out stirring for 15 min and then carrying out sonic dispersion. The compounding process utilizes 10% to 20% of alcohol amine, 8% to 17% of the industrial salt, 20% to 30% of the industrial waste and 48% to 60% of water; and ultrasonic time in the process is 10 min to 30 min. The active ingredients of the grinding aid obtained in the invention are greatly improved, and the grinding aid is uniform and stable, does not settle, and has good application prospects.

Description

technical field [0001] The invention relates to a method for improving the homogeneity of cement grinding aids, relates to the compounding field of cement concrete admixtures, and particularly belongs to the field of cement grinding aids production. Background technique [0002] At present, in order to reduce energy consumption and increase cement production in the process of cement production, the vast majority of cement enterprises in my country add a certain amount of grinding aids to achieve the goal of energy saving and emission reduction. The use of cement grinding aids can not only improve the performance of cement products, but also realize the comprehensive utilization of industrial solid waste raw materials. Therefore, the use of grinding aids is a major change in the cement industry, and it is also a response to the sustainable development path of high quality, high efficiency, low consumption, and environmental compatibility advocated by the country.
