Embodiment 1

[0025] (1) Extract artificial stone calcium-aluminum plate waste and quartz slate waste from the sedimentation tank, and pass the obtained waste mixture through a sieve with an aperture of 0.080mm, and control the residue at 12%, and then use a sieve with an aperture of 0.20mm Screening, the sieve residue is controlled at less than 1.0%, the sieve residue refers to the material that cannot pass through the sieve; pressure filtration keeps the water content of the waste at about 10%;

[0026] (2) Mixing and molding of materials: Take the above-mentioned 60kg of artificial stone waste, 15kg of cement, 4kg of activator, 5kg of fly ash, 0.02kg of high-efficiency water reducer, and 7kg of water, and add it to the wheel of the wheel mixer Grind and mix for 10 minutes to obtain a mixed material;

[0027] (3) Put the mixed material into the mold, put it on the vibrating table and vibrate for 20 seconds, and the molding pressure is 23Mpa;

[0028] (4) Put the mold containing the mixed...

Abstract

The invention relates to a method for producing autoclaved bricks from artificial stone plate wastes. The method comprises the steps of (1) taking the artificial stone calcium-aluminum plate wastes and quartz stone plates wastes out, mixing, sieving, and carrying out press filtering to obtain artificial stone wastes powder, wherein the water content of the wastes is controlled at 10% + / - 5% by press filtering; (2) weighing the following materials in parts by weight: 40-60 parts of artificial stone wastes powder, 10-20 parts of cement, 1-5 parts of activator, 5-10 parts of fly ash, 0.015- 0.03 part of an efficient water reducer, putting the above materials into a mixer, mixing, adding 5-11 parts of water, stirring uniformly to obtain a mixed material; (3) loading the mixed material into the mold, vibrating, molding under 20-30Mpa pressure, carrying out autoclave molding in an autoclave, curing, stripping and homogenizing. The strength and toughness of the autoclaved brick is improved by producing wall materials from industrial wastes according to the invention and double effects of environmental pollution and comprehensive and highly efficient utilization of wastes are reached.

Description

technical field [0001] The invention relates to a method for producing autoclaved bricks by using construction waste, and belongs to the technical fields of building material technology and waste utilization. Background technique [0002] As a new type of healthy and environmentally friendly product in line with the national sustainable development strategy, artificial stone panels were introduced into the domestic market in the 1980s. Although my country's artificial stone industry started relatively late, after more than ten years of rapid development, it has become the preferred material for cabinet countertops. The industry presents a very gratifying situation, and a consumer market with huge potential has been cultivated, ranking among the top in the world in terms of market size and application penetration rate. According to incomplete statistics, there are nearly a thousand large and small artificial stone manufacturers in the country. In 2010, the total sales of art...
