Novel cement admixture, and preparation method and application thereof

Abstract

The invention belongs to the field of comprehensive utilization of waste residues, and particularly relates to a novel cement admixture, and a preparation method and application thereof. By comprehensively utilizing cement industry high-alkali high-chlorine waste bypass snuffle ash, high-chlorine high-alkali kiln ash and other waste residues, the method can widen the application range of high-chlorine high-alkali raw materials and reduce the environmental pollution caused by industrial wastes; and other industrial wastes are simultaneously added to optimize the cement performance. The invention aims to provide a novel cement admixture which is prepared from the bypass snuffle ash or high-alkali high-chlorine kiln ash used as the raw material and papermaking white clay and carbide slag used as auxiliary materials. The novel cement admixture is prepared from the following components in parts by weight: 1 part of papermaking white clay, 1-2 parts of carbide slag and 0.5-3 parts of bypass snuffle ash. The method achieves the goal of comprehensively utilizing the bypass snuffle ash or high-chlorine high-alkali kiln ash, papermaking white clay, carbide slag and other waste residues.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of waste residues, and in particular relates to a novel cement mixture material and its preparation method and application. The present invention can expand the use of high-chlorine and high-alkali raw materials in the cement industry by comprehensively utilizing the high-alkali and high-chlorine waste in the cement industry to bypass the waste such as wind ash and kiln dust, reduce the pollution of industrial waste to the environment, and add other Industrial waste, optimization of cement properties. Background technique [0002] In the process of cement production, in order to reduce the cost of cement production, raw materials such as limestone, shale, sulfuric acid slag, cinder, bituminous coal and other raw materials used in the cement industry are generally obtained locally, and at the same time reduce the impurity content in the purchased raw materials as much as possible However, ...
