Problems solved by technology

[0003] At present, the production technology of light aggregate blocks is made by mechanical mixing. Because of the different densities of raw materials, high-density aggregates sink and low-density aggregates float during mixing, resulting in uneven mixing. Uniform, heavy blocks will appear heavy, reduce thermal insulation performance, and seriously affect the quality of lightweight blocks. The current acceptance criteria for light aggregate blocks are: thermal conductivity > 0.22w / m k, sound insulation > 45db, The pressure is less than 3.5MPa, the freeze-thaw resistance is qualified for 15 times, and the service life is less than or equal to 15 years

Abstract

The invention relates to the field of production of a building material, and particularly relates to a method for producing a lightweight block by using a black metal flotation mud. The method is characterized by comprising mixing, foam preparation, mixing and casting into a mold and feeding to a kiln to steam. The method comprises the following concrete operation steps: 1) mixing cement, black metal flotation mud and a ZQ-1 early strength agent to prepare slurry; (2) foam preparation; 3) pouring the slurry in the step 1) and the foam in the step 2) into a mold on which a release agent is coated after agitating evenly; and (4) feeding the fully cast mold into a curing kiln to steam, demolding and cutting after discharging out of the kiln, and stacking the products, checking and delivering qualified products. Compared with the prior art, the method has the advantages that the phenomenon of uneven intensity of a lightweight aggregate building block is thoroughly improved, the product quality is improved, the compressive strength of the product is 3.5-10.5MPa, the dry density is 400-1,000kg / m<3>, the heat conductivity coefficient is 0.06-0.22w / m.k, and the service life is greater than or equal to 50.

Description

technical field [0001] The invention relates to the technical field of building material production, in particular to a method for producing lightweight blocks by using ferrous metal flotation mud. Background technique [0002] The flotation process is mainly used in ferrous metal beneficiation processing. Commonly used flotation machines include mechanical agitation flotation machines, inflatable agitation flotation machines and flotation columns. Over the years, the flotation mud has been mainly piled up in the form of tailings dams, which cannot be effectively utilized and cause great damage to the environment. In order to improve the utilization of ferrous metal flotation mud, the ferrous metal flotation mud can be used in the production of building materials. [0003] At present, the production technology of light aggregate blocks is made by mechanical mixing. Because of the different densities of raw materials, high-density aggregates sink and low-density aggregates f...
