Green and environment-friendly brick for building and making technology thereof

Abstract

The invention discloses a green and environment-friendly brick for building and a new technology production mode for preparation of the green and environment-friendly brick for building, and the green and environment-friendly brick for building uses calcined oyster shell powder to replace part of expensive building raw materials such as lime, cement and the like. Compressive strength and dry density and other technical parameter requirements of a product are ensured, meanwhile mixing amounts of the cement and the lime are reduced, the production cost is reduced, the oyster shell powder is mixed for mixed grinding with tailing sand to prepare good-performance mortar, so that a tailing sand early-stage processing technology requires that the fineness needs to increase from 0.08 mm-sieve screen residue weight of 30% to 60%, the tailing sand processing time and processing power consumption are reduced, the energy is saved, oyster shell produced by coastal oyster breeding is effectively used and duly processed, and the environment is improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a green environmental protection brick for building and a manufacturing process thereof. Background technique [0002] At present, the production process of environmentally friendly bricks has become more and more mature. Most of them use tailings sand, lime, gypsum, cement and other additives as the main raw materials, add water for mixing, and then put the mixed materials into the brick mold. The constant temperature room is left to stand for a period of time, and then the materials after standing are subjected to high temperature and high pressure autoclaving to make environmentally friendly bricks with the characteristics of heat preservation, fire prevention and light weight. According to the traditional formula for the production of environmentally friendly bricks, in order to ensure the stability of production and the technical parameters of the product such as ...

AI Technical Summary

Problems solved by technology

However, a large number of oyster shells left in the process of oyster production and processing have not been effectively utilized and properly disposed of, seriously polluting the rural environment and directly affecting the improvement of urban and rural living environments and the construction of new countryside.
