Method for producing autoclaved bricks from artificial stone plate wastes

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.

AI Technical Summary

Benefits of technology

This patented technology allows for the preparation of synthetic stones made up mostly calcium silicate (CaSi02) instead of other mineral sources like clay or sandstone. By adding certain chemical agents at specific times along the manufacturing route, the resulting rocks have improved properties such as strength without losing their shape when exposed to moisture. Additionally, this new type of rock has better resistance against fire damage than traditional ones due to less volatile ingredients used therefor. Overall, this method provides technical benefits over existing methods while minimizing resource usage and costs associated with producing them.

Problems solved by technology

This patented describes various methods for reclaiming waste from manmade stones. However, current techniques involve disposal of entire houses containing artificial stone products, leading to significant resource losses and increased costs associated with their disposal. There is currently no effective solution for effectively reuse scraps creation through innovations like automobile construction projects.
