Abstract

The invention belongs to the technical field of cement additives, in particular to an enhanced composite cement grinding aid. The enhanced composite cement grinding aid is prepared from the following raw materials in parts by weight: 20-30 parts of triethanolamine, 10-20 parts of triisopropanolamine, 8-16 parts of sodium tripolyphosphate, 2-6 parts of alkyl glycoside, 1-6 parts of zinc stearate, 0.6-2.2 parts of sodium sulfosuccinate and 35-55 parts of water. With the adoption of the enhanced composite cement grinding aid, the strength of cement at ages of 1 day, 7 days and 28 days can be significantly improved, and defects in the prior art are overcome.

Description

technical field [0001] The invention belongs to the technical field of cement admixtures, in particular to an enhanced cement composite 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 th...
