Method for making permeable bricks by using construction wastes

Abstract

The invention discloses a method for making permeable bricks by using construction wastes. The method comprises the following production steps: taking the construction wastes and calcites, and crushing; adding obtained crushed construction waste particles and sands into a stirring machine, and stirring; adding cement to the stirring machine, and carrying out vibrating mixing to prepare construction wastes mixed particles; and mixing and stirring a sandstone mixture, cement, water and the construction wastes mixed particles to prepare a mixed raw material; taking xanthan gum and water, mixing to form a gum solution, immersing calcite particles in the gum solution, filtering out the gum solution, and air-drying to form calcite micelles; adding the calcite micelles to the mixed raw materials, mixing and stirring, and processing the above obtained stirred mixed material to make green bricks; and immersing the green bricks in water, drying the immersed green bricks, decomposing the calcite, and cooling to normal temperature in order to make the permeable bricks. The permeable bricks made in the invention have the advantages of high strength, strong permeable ability, environmentally-friendly utilization of the construction wastes, and realization of performances according with relevant quality standard requirements.

Description

technical field [0001] The invention relates to building materials, in particular to a method for making permeable bricks from construction waste. Background technique [0002] Traditional bricks are made by adding sandstone and then compacted. As the performance requirements of permeable bricks, the brick body should not be too dense to affect the water permeability of the brick body; it should not be too loose to avoid insufficient compressive resistance. At present, with the acceleration of urbanization, more and more waste materials are generated in construction, which are usually disposed of by filling up, lacking effective and environmentally friendly disposal methods. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for making permeable bricks from construction waste. [0004] The method for making permeable bricks from construction waste of the present invention comprises the following production st...
