Cement grinding aid and using method thereof

Abstract

The invention discloses a cement grinding aid. The cement grinding aid is prepared from the following substances by mass fraction: 5-10% of triethanolamine, 10-15% of triisopropanolamine, 20-30% of polymerized lipoxidized alcohol, 5-10% of a sodium thiocyanate solution, 30-60% of a composite glycerol solution and 10-20% of molasses. A using method for the cement grinding aid is as follows: adding 0.3-0.8 kg of the cement grinding aid into every ton of cement. The cement grinding aid disclosed by the invention is energy-saving and efficient, can be used for improving the strength at each stage of the cement, increasing the cement yield and improving other cement indexes; moreover, the cement grinding aid is good in compatibility with a concrete admixture, so that the integral cost performance is higher than that of a market product. In the components of the cement grinding aid, industrial wastes and standard substances are reasonably combined to achieve a high value with low cost; substantial action and characteristics of the product are shown in improving the grinding efficiency, increasing the yield, increasing the strength and lowering the energy consumption.

Description

technical field [0001] The invention belongs to the field of cement production, in particular to a cement additive, more specifically to a cement grinding aid and a use method thereof. Background technique [0002] At the end of the 1920s and the beginning of the 1930s, the British J.F. Goddard (J.F.Goddard) used resin as a cement grinding aid and obtained a British patent; then it was popularized and applied in the market. The early concept of grinding aid is: in order to improve the water resistance, early strength and processability of cement series products, test and use mineral oil, animal oil and petroleum cracking residue, use inert and adsorbable minerals as carriers, and mix A powdery mixture made of calcium-containing substances such as hydrochloric acid, calcium chloride, and limestone. The use of these additives improves the water resistance and processability in the production of cement series products. [0003] Nowadays, more than 80% of the manufacturers in ...

AI Technical Summary

Problems solved by technology

The formula mainly consists of alcohols, alcohol amines, lignin sulfonates, fatty acids and their salts, alkyl sulfonates and other single or compound products; however, the production cost is high and limited by the use of cement ingredients. Can't better adapt to the various demand standards of different cement companies, can't get the best effect of its own products, so that the market promotion is limited
