Abstract

A composite admixture for cement or high-performance concrete and a preparation method thereof. The admixture comprises silicon manganese slag, slag, limestone, furnace slag or fly ash, and grinding aids, and the mass ratios are: 50-70 of silicon-manganese slag, 10-20 of slag, 8-15 of limestone, 10-15 of furnace slag or fly ash, and 0.5 or 2 of grinding aids. The preparation method comprises: adding the raw materials according to the ratios into a ball mill, grinding till the grinding fineness meets that the Blaine specific surface area is not less than 400 m2/kg or 450 m2/kg so as to obtain the silicon manganese slag-based composite admixture for cement or high-performance concrete. The preparation of the admixture can use a large amount of industrial waste residues - silicon manganese slag discharged from the production of silicomanganese alloy, and the admixture is prepared with a proper amount of slag, limestone, furnace slag or fly ash, and a small amount of grinding aids, which has remarkable economic effect, and outstanding social benefits and environmental benefits.

Description

technical field [0001] The invention belongs to the production technology of cement and high-performance concrete, and in particular relates to a silico-manganese slag-based admixture for cement or high-performance concrete and a preparation method thereof. Background technique [0002] Regarding the use of silicomanganese slag in cement, there is a small amount of individual components added to the grinding head, such as an article in the fifth issue of "China Cement" in 2003 "Production of Ordinary Portland Water Cement with Silicomanganese Slag". , the article claims to use silicomanganese slag to produce clinker, not as admixture. In addition, in the "China Cement Technology Network" there is an article "Development of Fly Ash Less Clinker Composite Cement", the author is Ren Sumei and others. It introduces the preparation of high-volume fly ash-less clinker composite Portland cement, which is made from ordinary fly ash, silico-manganese slag and a small amount of gypsu...
