Abstract

The invention relates to the technical field of cement additives, in particular to a liquid cement grinding aid. The liquid cement grinding aid is prepared from, by weight, 20-30 parts of triisopropanolamine, 10-20 parts of sulfated coconut oil fatty acid monoethanolamide sodium, 8-16 parts of borax, 2-6 parts of ethyl acetate, 1-6 parts of Arabic gum, 0.6-2.2 parts of zinc stearate and 35-55 parts of water. The liquid cement grinding aid is efficient, stable in performance and capable of lowering grinding energy consumption and improving the cement strength and the durability of concrete.

Description

technical field [0001] The invention relates to the technical field of cement admixtures, in particular to a liquid cement grinding aid. Background technique [0002] Cement grinding is a necessary process and key link in cement production. Its energy consumption and electricity consumption account for 30% of the total energy consumption of cement production and more than 70% of the total electricity consumption. At present, the national low-carbon environmental protection requirements are getting higher and higher. Sluggish prices, rising prices of raw materials and energy, and fierce competition in the industry have stretched the profitability of cement companies. Therefore, energy conservation and emission reduction, development of low-carbon economy, cost reduction, and improvement of grinding aid performance are urgent problems to be solved by the cement industry. In order to reduce energy consumption and improve grinding efficiency, people usually take the following t...
