A kind of cement modified grinding aid containing mannitol and ethyl silicate and its preparation method and application

Abstract

The invention provides a cement modifying grinding aid containing mannitol and ethyl silicate, and a preparation method and applications thereof. The cement modifying grinding aid containing mannitoland ethyl silicate comprises, by weight, 7 to 11% of triethanolamine, 5 to 8% of sorbitol, 1 to 3% of mannitol, 1 to 3% of ethyl silicate, 7 to 15% of sodium formate, 3 to 5% of molasses, and the balance water. The cement modifying grinding aid is excellent in grinding assisting, enhancing, and energy saving effect, is capable of improving cement adaptability and construction performance, ensuringcement concrete product quality stability, and is excellent in economical and social benefits.

Description

technical field [0001] The invention relates to the technical field of cement additives, in particular to a cement modified grinding aid containing mannitol and ethyl silicate and its preparation method and application. Background technique [0002] Cement grinding aid is a chemical additive to improve the grinding effect and performance of cement, and it is added in a small amount during the grinding process of cement clinker. Cement grinding aids can significantly improve the grinding process, significantly increase the grinding efficiency and reduce energy consumption. It is of great significance to reduce the cost of enterprises and improve market competitiveness. It has become an indispensable raw material in the grinding production process of many cement manufacturers. one. [0003] Adding grinding aids during cement grinding will increase the strength of cement and reduce production costs, but it will lead to poor compatibility between cement and concrete admixtures ...

AI Technical Summary

Problems solved by technology

[0003] Adding grinding aids during cement grinding, although the strength of cement increases and the production cost decreases, it will lead to poor compatibility between cement and concrete admixtures (such as water reducers), and the use effect of cement will be significantly worse

At present, the compatibility of cement and admixtures has become the biggest problem in the concrete industry. It will not only affect the effect of cement and admixtures, but also affect the performance indicators of cement concrete and the quality of concrete projects.
