Abstract

The invention relates to water permeable bricks produced by using building waste residue and a manufacturing method thereof. The manufacturing method is characterized by comprising the following steps: mechanically stirring a lower-layer brick material, which is formed by uniformly mixing building waste residue powder, waste glass powder, fly ash, portland cement, calcium oxide, calcium sulfate, sodium chloride, rosin pyrolytic polymer, calcium sulfonate, sodium sulfate, sodium aluminate and water, to be in a moist state, then performing mechanical vibration extrusion to form lower-layer bricks, further uniformly distributing an upper-layer brick material, which is formed by uniformly mixing marble waste residue powder, bentonite, talcum powder, iron oxide and water, on the upper parts of the lower-layer bricks through a secondary material distributing machine for forming a layer of surface material, then preparing water permeable adobe under the pressure of 25-30MPa, further performing steam curing, heating, keeping temperature constant and naturally cooling down to prepare water permeable brick products by using the building waste residue. The products have multiple functions of having water permeability, gas permeability and water retention property, reducing the temperature, reducing the noise, regulating the climate, eliminating the heat island effect of an urban, improving the air quality, keeping the circulation of surface water and the like, and have the advantages and effects of no pollution, low cost and good benefits.

Description

technical field [0001] The invention relates to a permeable brick produced from construction waste residue, specifically, it is a permeable brick produced mainly from construction waste residue, waste glass, fly ash and marble waste residue, and belongs to the field of waste treatment. [0002] The invention also relates to a manufacturing method of the construction waste slag permeable brick. Background technique [0003] With the rapid development of my country's economy and the continuous improvement of people's living standards, people's requirements for living environment are also getting higher and higher. Since most of the surface of a modern city is covered by buildings, concrete and floor tiles, although the city streets are clean and tidy, these solid plates are not conducive to the infiltration of rainwater into the ground in a timely manner, and it is easy to generate flooding water in the event of heavy rain or heavy rain. Flooding problem. Most cities in the ...
