Non-sintered water permeable brick and preparation method thereof

Abstract

The invention discloses a non-sintered water permeable brick and a preparation method thereof. The non-sintered water permeable brick comprises, by weight, 25-30 parts of scrap steel, 15-20 parts of red mud powder, 30-40 parts of limestone, 5-10 parts of cement, 0.5-1 part of redispersible latex powder and 8-15 parts of water. The preparation method includes compounding, stirring, green brick making and curing. The non-sintered water permeable brick has the advantages of excellent water permeability, wide availability to raw materials, low cost, simple production technology, environment protection and energy conservation.

Description

technical field [0001] The invention relates to a building material, in particular to a non-sintering permeable brick and a preparation method thereof. Background technique [0002] With the continuous progress of society, more and more urban surfaces are covered by buildings and concrete and other impermeable ground paving, forming an "urban desert". These hardened pavements make it difficult to exchange heat and moisture between the ground surface and the air, and the ability to naturally regulate the temperature and humidity of the urban ground is significantly reduced. In rainy days, prevent rainwater from infiltrating directly into the ground, causing water to accumulate everywhere, affecting the comfort and safety of roads, and blocking the way for rainwater to directly replenish groundwater, making it difficult for urban groundwater to rise, directly affecting the healthy growth of urban surface vegetation. Greening is difficult, aggravating the city's drought and wa...

Problems solved by technology

[0004] Most of the existing permeable bricks use clay as the binder, which needs to be sintered during the preparation process, which wastes a lot of coal resources and destroys the land.
