Abstract

The invention discloses a high-strength clinker calcined from limestone mine interlayer ingredients, and particularly relates to the field of cement clinker. The high-strength clinker comprises the following components by weight: 80-90 parts of limestone, 4-10 parts of a mine yellow sandstone interlayer material, 2-6 parts of a mine red sandstone interlayer material, 2-5 parts of an associated interlayer material, and 1.5-3 parts of copper slag. The invention aims to reduce the SM of the clinker, improve the KH and IM of the clinker, and improve the burnability of the clinker, thereby enhancing the clinker strength, avoiding purchasing silicon-aluminum materials and lowering the material cost of the ingredients. A mine interlayer is fully utilized, zero waste discharge of a mine can be achieved, the mining cost is reduced, and the comprehensive creation effect is achieved.

Description

technical field [0001] The invention relates to the field of cement clinker, more specifically, the invention relates to a method of calcining high-strength clinker by using limestone mine interlayer ingredients. Background technique [0002] Cement is a cementitious material made by mixing and grinding limestone, silica-alumina materials, iron materials, etc. in proportion, then calcining clinker at high temperature, adding mixed materials, retarders and other materials to the clinker, and grinding to a certain fineness. . With the continuous development of the construction industry, the demand for cement is also increasing. [0003] During the mining process of limestone mines, many interlayers will be encountered, mostly silicon-aluminum materials and high-magnesium limestone. Considering the large amount of interlayer waste discharge, it is bound to increase the mining cost of the mine. Find a way to apply the silicon-aluminum interlayer to the ingredients, which not ...
