Method for grinding cement admixture and grinding aid for cement admixture

Abstract

The invention provides a cement mixture grinding method and a cement mixture grinding aid. The method includes: subjecting a to-be-grinded cement mixture and the cement mixture grinding aid to grinding treatment together; specifically, the cement mixture grinding aid contains waste saponification lye generated in preparation of cyclohexanone by cyclohexane oxidation. The cement mixture grinding method provided by the invention can take the waste saponification lye generated in preparation of cyclohexanone by cyclohexane oxidation as the grinding aid for cement mixture grinding.

Description

technical field

[0001] The invention relates to a method for grinding cement admixture and a grinding aid for cement admixture. Background technique

[0002] In order to improve cement performance, adjust cement strength grade, increase cement production, etc., artificial or natural mineral materials are added, which is called cement mixture. Most of the currently used cement mixtures are industrial waste residues. Mixed materials are usually divided into two categories: active mixed materials and inactive mixed materials according to their different properties, among which active mixed materials are used in the largest amount. Commonly used active mixed materials include granulated blast furnace slag, pozzolanic mixed materials and fly ash, etc., while inactive mixed materials include fine powder ground from quartzite, sandstone, etc. In the production process, the grinding process consumes a lot of energy, and the utilization rate of energy is extremely low, resulting in...
