Problems solved by technology

[0003] (1) The hardened road surface will cause serious environmental pollution: when it rains heavily, the rainwater will take away a large amount of urban pollutants, such as oil, garbage, gravel, silt, pesticides sprayed on urban grasslands and parks, etc., through the hardened road surface. Rivers and lakes receiving torrential rain are polluted by treatment
[0004] (2) The groundwater level drops due to the hardening of the road surface: groundwater is an important resource for maintaining urban development. Due to the impact of the hardening of the road surface, the groundwater cannot get the necessary supplement, and the water level continues to drop, which in turn leads to the subsidence of the foundation and the collapse of houses.
[0005] (3) The hardened road surface leads to the deterioration of the urban environment: because the hardened ground cannot absorb precipitation, the rainwater is wasted in vain. When the rainy season is over, the local area will suffer from drought and water shortage, and fall into a vicious circle
The use of industrial waste as the main raw material to produce low-temperature ceramic permeable bricks has not been reported

Abstract

The invention relates to a low temperature ceramics non-watertight brick made of solid waste slag and a manufacture method thereof, belonging to the technical field of building materials. The mixture ratio by weight of the components of the low temperature ceramics non-watertight brick is that waste slag gelled material to waste slag skeletal material to porogenic agent to activating agent to addition agent to paint to water is equal to 100:200-800:0.1-40:13-50:0.2-3.0:0.1-7.0:1-20. After the process, mixture, vibrating forming and maintenance process for the raw materials, the raw materials are prepared into the low temperature ceramics non-watertight brick with a filled pore by taking the low temperature ceramics mineral as the matrix phase and taking the inorganic waste slag particle as the wild phase. Compared with the prior art, the low temperature ceramics non-watertight brick has the advantages of high strength, good permeability of water, high salvage value, simple process, low cost, environment protection and natural resources reservation, etc. which can be widely applied to the laying of urban highways.

Description

technical field [0001] The invention relates to a method for producing low-temperature ceramic permeable bricks from solid waste, which belongs to the technical field of building materials. Background technique [0002] As we all know, urban streets and streets are mostly paved with impermeable materials such as cement concrete, asphalt, stone, and ceramic tiles. This hardened pavement is no longer suitable for the city to maintain a good ecological environment. The reasons are: [0003] (1) The hardened road surface will cause serious environmental pollution: when it rains heavily, the rainwater will take away a large amount of urban pollutants, such as oil, garbage, gravel, silt, pesticides sprayed on urban grasslands and parks, etc., through the hardened road surface. Rivers and lakes that receive heavy rain are polluted by treatment. [0004] (2) The groundwater level drops due to the hardening of the road surface: groundwater is an important resource for maintaining u...
