Problems solved by technology

There are still many problems in the use of grinding aids in my country, such as chloride salts bring great safety hazards to the durability of cement and concrete; the quality of grinding aids is unstable, and the amount of mixing is large, which leads to fluctuations in cement quality, etc.
In the prior art, the prominent feature of using triethanolamine in cement grinding aids is that it can increase the mortar strength of cement for 1 day, but it does not contribute to the strength of 28 days and beyond; many cement grinding aids also use triethanolamine to strengthen cement 7 days, 28 days or later, but triethanolamine cannot increase the early strength of cement within 1 day or 7 days

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...
