Problems solved by technology

[0004] In the prior art, the aggregate finer than 200 mesh fine powder used in mortar should not exceed 4%, otherwise the mortar will crack quickly during the drying process
Therefore, although industrial dust contains a large amount of beneficial substances, it still cannot be applied in the field of dry-mixed mortar production.

Abstract

The invention discloses dry-mixed masonry mortar for industrial dust, belonging to a premixed dry-mixed masonry mortar material for a building. The dry-mixed masonry mortar is prepared from the following ingredients in parts by weight: 8-12 parts of cement, 10-20 parts of industrial dust, 0-3 parts of coal ash, 65-82 parts of aggregate, 0.3-0.5 part of compound activator, 0.08-0.1 part of compound water-retaining agent, 0.1-0.2 part of crack-resisting agent and 0-0.3 part of water repellent agent. Compared with the prior art, the dry-mixed masonry mortar can be additionally added with 10-20 percent fine powder with granularity of less than 200mu without causing cracking, therefore, the traditional provision that the addition amount of the fine powder with the granularity of less than 200mu is not more than 4 percent is thoroughly broken, and a bran-new path for utilization of industrial dust is developed.

Description

technical field [0001] The invention relates to a ready-mixed dry-mixed mortar material for construction, in particular to an industrial dust dry-mixed mortar. Background technique [0002] With the development of society, people's requirements for project quality, environmental protection requirements and civilized construction are constantly improving, and the advantages of dry-mixed mortar are favored by more and more people. [0003] Mine mining, sandstone crushing, block grinding, factory production, etc. form a large amount of ultra-fine dust finer than 200 mesh every year, especially in the process of gold mining, a large amount of tailings fine powder of about 400 mesh is formed, which occupies a large amount of Cultivated land seriously pollutes the air. [0004] In the prior art, the aggregate finer than 200 mesh fine powder used in the mortar should not exceed 4%, otherwise the mortar will crack quickly during the drying process. Therefore, although industrial d...
