Abstract
The invention relates to the field of cement admixtures, and particularly discloses a cement grinding aid and cement using the cement grinding aid, and the cement grinding aid is prepared by stirring and mixing the following raw materials in parts by mass: 10-20 parts of triisopropanolamine, 10-15 parts of ethylene glycol and 10-15 parts of gluconic acid. The preparation method of the cement grinding aid comprises the following steps: putting the cement grinding aid and cement raw materials into a ball mill according to the mass ratio of 1: 250, and grinding for 30 minutes to obtain cement, the cement grinding aid can be used for cement production, and has the advantage of improving the strength of cement.
Description
technical field [0001] The application relates to the field of cement admixtures, more specifically, it relates to a cement grinding aid and cement using the cement grinding aid. Background technique [0002] Cement grinding aid is an important additive in cement, which needs to be added to cement clinker in a certain proportion during the production process. [0003] Cement grinding aids are composed of one or several surface active substances. The application effect of most cement grinding aids shows that cement grinding aids can reduce cement particle size, increase specific surface area, improve some physical and chemical properties of cement, and reduce dust particles. Grinding power consumption and so on. [0004] In view of the above-mentioned related technologies, the inventor believes that cement grinding aids can improve the grinding efficiency of cement particles, reduce the cement particle size, increase the specific surface area of cement particles, and promo...
