Abstract

The invention discloses a method for preparing a cement admixture by use of electrolytic manganese residue and a product and an application. The method comprises the following steps: breaking the electrolytic manganese residue into the particle size of 5-15mm; calcining the broken electrolytic manganese residue in a fluidized-bed furnace for 1-1.5 hours at 450-750 DEG C to obtain the cement admixture. The obtained cement admixture can be applied to the preparation of cement, namely that the cement is prepared by grinding 5-50% of cement admixture and 95-50% of Portland cement clinker by weight. Through the invention, waste utilization and comprehensive treatment of the electrolytic manganese residue can be realized.

Description

technical field

[0001] The invention relates to a method, product and application for preparing cement admixture by using electrolytic manganese slag, and belongs to the field of comprehensive utilization of industrial waste residue and cement building materials. Background technique

[0002] Manganese is one of the dominant mineral resources in Guizhou Province. Songtao County in Guizhou Province, adjacent to Huayuan County in Hunan Province and Xiushan Autonomous County in Chongqing are known as the "Manganese Triangle" of China's manganese mines. Manganese ore resources are valuable resources in this region, and its reserves account for more than 30% of the country's total reserves. 90% to 95% of manganese production is used in the iron and steel industry, and its use is mainly as a deoxidizer and desulfurizer in the process of ironmaking and steelmaking, as well as for the manufacture of alloys. In addition, chemical industry, light industry, building materials and othe...
