High effect composite additire of cement

Abstract

An efficient composite additive for cement is prepared from sodium hydroxide, calcium saccharide, activating agent, triethanolamine and water through proportionally mixing. It can greatly increase the pulverizing efficiency and improve the physical and mechanical performance of cement.

Description

Technical field [0001] The invention relates to a cement additive, in particular to a high-efficiency composite additive which is mixed in cement clinker and then ground in the process of cement production. Background technique [0002] At present, commercially available cement additives are mostly composed of various organic and inorganic materials such as sodium sulfate, sodium dichromate, plasticizers, active agents, grinding aids and strengthening agents, and are mixed with clinker in the cement production process. In the powder after pulverization, it is felt that this additive has poor high temperature resistance in practice. The method of mixing it in the ball mill cannot improve the grinding efficiency, the mixing is uneven, and the clinker saving is poor. Although it plays a role in improving the physical and mechanical properties of cement It has a certain positive effect, but it is still unsatisfactory when used in important and high-index concrete projects.

[0002] At present, commercially available cement additives are mostly composed of various organic and inorganic materials such as sodium sulfate, sodium dichromate, plasticizers, activators, grinding aids and strengthening agents, and are mixed with clinker in the cement production process. In the powder after pulverization, it is felt that this additive has poor high temperature resistance in practice, and the method of mixing it in the ball mill cannot improve the grinding efficiency, the mixing is uneven, and the clinker saving range is relatively poor. Although it plays a role in improving the physical and mechanical properties of cement It has a certain positive effect, but when used in important and high-index concrete projects, it is still unsatisfactory
