Problems solved by technology

The hardened ground is like a diaphragm laid on the soil. Precipitation can only flow on it and cannot be absorbed internally. As a result, the water seepage capacity of the urban ground is getting worse and worse. Once a large amount of rainfall occurs, it is easy to form waterlogging

Embodiment 1

[0029] Embodiment 1: as figure 1 As shown, the method for making permeable bricks from waste concrete is characterized in that it comprises the following production steps:

[0030] (1) After the waste concrete is crushed or hammered by a pressure testing machine, it is screened through a square hole sieve with an aperture of 26.5 mm to obtain the oversize and undersize of the square hole sieve with an aperture of 26.5 mm;

[0031]① Firstly, crush the material on the square-hole sieve with an aperture of 26.5mm using a jaw crusher, and the discharge port of the jaw crusher is 25mm wide; then sieve through a square-hole sieve with an aperture of 4.75mm to obtain The sieve on the square hole sieve with a hole diameter of 4.75mm is the continuous particle size recycled coarse aggregate with a particle size of 5-25mm;

[0032] ②In addition, the undersize of the square hole sieve with an aperture of 26.5mm is sieved with a square hole sieve with an aperture of 9.5mm to obtain the ...

Embodiment 2

[0043] Embodiment 2: Different from Example 1, in the method for making permeable bricks from waste concrete, the calcite is crushed to a particle size of 3mm, and xanthan gum and water are mixed into a glue with a weight ratio of 1:20, and Immerse calcite particles with a particle size of 3mm in the glue solution, then filter the soaked calcite particles through a 10-mesh sieve to remove excess glue solution, and dry them at 25°C for 1.2 hours to form calcite particles wrapped with a glue layer on the outer surface ; Then in step (2), add calcite granules accounting for 4% by weight of cement to the mixer, and stir together with recycled aggregate, water and cement at a temperature of 60°C and a humidity of 30% at a horizontal speed of 1100rpm for 45 Seconds; then enter step (3), after the mixed material after mixing is machine-pressed to make bricks, immerse the bricks in water, then change the water every 10 minutes, repeat 4 times; dry the soaked bricks, Calcite was decomp...

Abstract

The invention discloses a method for manufacturing a water permeable brick from waste concrete, and a pavement method of the water permeable brick. The method for manufacturing the water permeable brick from the waste concrete disclosed by the invention comprises the following steps: taking the waste concrete and crushing, so as to prepare regenerated fine powder and regenerated aggregate; adding the regenerated aggregate, water and cement to a blender and stirring; carrying out mechanical pressing on stirred hybrid materials, so as to prepare a green brick; manufacturing the water permeable brick after naturally maintaining. The invention also provides the pavement method of the water permeable brick. The pavement method of the water permeable brick comprises the following steps: tamping a natural soil layer; paving a mixed soil layer on the natural soil layer; paving the regenerated fine powder on the mixed soil layer as a cushion; finally paving the water permeable brick on the cushion. The water permeable brick is prepared by using the waste concrete, and is creatively paved; a lot of waste concrete can be utilized; the brick surface can absorb about 35% of surface water; underground water is evaporated in a sunny day; the ground temperature can be reduced; the content of pollutants such as particulate matters (PM2.5) in pavement air is reduced.

Description

technical field [0001] The invention relates to building materials, in particular to a method for making permeable bricks from waste concrete and a laying method for the permeable bricks. Background technique [0002] Concrete engineering is the leading project of large-scale civil construction. Concrete is a material widely used in building materials. It occupies an extremely important position in the construction industry and has always been valued by people. In recent years, with the development of social economy, my country's construction industry has developed rapidly like never before, new buildings are constantly being built, and the amount of concrete is increasing. At the same time, many old buildings are destroyed because they do not meet the requirements of modern economic development Demolition is required, resulting in a large amount of construction waste. According to statistics, the construction waste produced by demolition of buildings in our country reaches ...
