Problems solved by technology

[0003] On the other hand, more and more buildings cover the urban ground, making it impossible for urban precipitation to penetrate into the ground, and it is also difficult for groundwater to evaporate, thereby destroying the urban water cycle process and forming an urban "heat island effect". Since urban precipitation cannot penetrate into the ground, In rainy weather, it is easy to form urban waterlogging, which brings great inconvenience to the life of urban residents

Embodiment 1

[0020] An environmentally friendly permeable brick prepared from recycled materials from construction waste. The mass components of the permeable base are: 40 parts of recycled fine aggregate, 30 parts of recycled sand, 5 parts of fly ash, 15 parts of cement, and 0.5 parts of water reducer , 13 parts of water; the mass components of the permeable surface layer are: 70 parts of reclaimed sand, 20 parts of cement, 7 parts of fly ash, 2 parts of mineral pigment, 0.5 part of water-permeable agent, 0.8 part of water-reducing agent, and 17 parts of water.

[0021] Its preparation process is as follows:

[0022] (1) Prepare cementitious base material and wet base material: Stir cement and water reducer evenly, add fly ash to mix to prepare cementitious base material; mix recycled fine aggregate and recycled sand evenly, add 3~ 5 parts water, mixed to make a wet base material;

[0023] (2) Prepare the concrete base material: mix the gel base material and the wet base material in step...

Embodiment 2

[0029] An environmentally friendly permeable brick prepared from recycled materials from construction waste, its preparation method is basically the same as in Example 1, the difference is that the mass components of the permeable base used are: 50 parts of recycled fine aggregate, 30 parts of regenerated sand, fly ash 3 parts, 10 parts of cement, 0.5 parts of water reducing agent, 15 parts of water; the mass components of the permeable surface layer are: 65 parts of reclaimed sand, 15 parts of cement, 5 parts of fly ash, 1.5 parts of mineral pigment, and 0.3 parts of water permeable agent , 0.8 parts of water reducer, 10 parts of water.

Embodiment 3

[0031] An environmentally friendly permeable brick prepared from recycled materials from construction waste, its preparation method is basically the same as in Example 1, the difference is that the mass components of the permeable base used are: 60 parts of recycled fine aggregate, 30 parts of regenerated sand, fly ash 8 parts, 20 parts of cement, 0.8 parts of water reducing agent, 15 parts of water; the mass components of the permeable surface layer are: 70 parts of reclaimed sand, 30 parts of cement, 10 parts of fly ash, 3 parts of mineral pigment, 0.5 parts of water permeable agent , 1 part of water reducer, 20 parts of water.

Abstract

The invention relates to an environmentally friendly water seepage brick prepared from recycled construction waste materials, comprising a water seepage base layer and a water seepage surface layer, the thickness of the water seepage base layer is 40-60 mm, the thickness of the water seepage surface layer is 10 mm to 15 mm, and the water seepage base layer and the water seepage surface layer are pressed bricks Machine compact pressing molding, water seepage base includes mass parts: 40~60 parts of recycled fine aggregate, 20~30 parts of recycled sand, 3~8 parts of fly ash, 10~20 parts of cement, 0.3~0.8 parts of alkaline water agent parts, water 10~15 parts, water seepage surface layer includes: reclaimed sand 65~80 parts, cement 15~30 parts, fly ash 5~10 parts, mineral pigment 0.5~3 parts, water permeable agent 0.3~1 part, water reducer 0.5~1 part, 10~20 parts of water. The water seepage brick obtained by the invention has the advantages of environmental protection, energy saving, low price and the like, and can also realize the double effect of water permeability and water retention of the water seepage brick.

Description

technical field [0001] The invention relates to the technical field of water seepage bricks, and more particularly relates to an environmentally friendly water seepage brick prepared from recycled construction waste materials. Background technique [0002] With the rapid development of urbanization in my country, on the one hand, there are more and more construction wastes. In order to quickly and cost-effectively dispose of large quantities of construction wastes, builders usually stack and bury waste solid materials randomly, occupying land resources and reducing The quality of the soil also pollutes the surrounding surface water and groundwater, affecting the ecological environment. In recent years, some more developed cities have begun to pay attention to the adverse impact of construction waste, and have recycled and reused construction waste. [0003] On the other hand, more and more buildings cover the urban ground, making it impossible for urban precipitation to pene...
