Abstract

A grinding-promoting and strengthening agent of cement is prepared from triethanolamine (0.8-5 Wt portions), anhydrous sodium sulfate (20-30), powdered coal ash (10-18), sodium carbonate (6-10), sodium chloride (25-33), gypsum (18-25) and sodium carbonate (8-15).

Description

technical field [0001] The invention relates to an admixture in cement production, in particular to a cement grinding aid enhancer and a preparation method thereof, belonging to the field of cement production. Background technique [0002] During cement production, it is often necessary to add an admixture that aids grinding and strengthens cement strength, in order to achieve the purpose of increasing the unit output of cement production, enhancing the strength of cement products, and saving costs. There are many kinds of existing cement grinding aid enhancers, but the effects of aiding grinding, strengthening cement strength and saving production cost are not ideal enough. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and to provide a cement grinding aid that can effectively improve the strength of cement products and save production costs in addition to having a good grind...
