Problems solved by technology

[0002] At present, the paving materials of urban roads and squares include cement block bricks, ordinary ceramic sintered bricks, concrete pavement, asphalt pavement, etc., which basically have no water permeability. Vehicles and pedestrians cause a lot of inconvenience. On the other hand, stagnant water cannot seep into the ground through the surface, and the groundwater resource declines year by year. The water level drops sharply, and the soil moisture suffers great damage, endangering the ecological environment on which people depend.

Abstract

A water-permeable moisture-preserving brick for pavement is made up of granular aggregate and high-plasticity clay powder through proportionally mixing, adding water, die pressing and calcining at 1100-1250 deg.C.

Description

technical field [0001] The invention provides a method for preparing a water-permeable and moisturizing pavement brick, which belongs to the technical field of building material production. Background technique [0002] At present, the paving materials of urban roads and squares include cement block bricks, ordinary ceramic sintered bricks, concrete pavement, asphalt pavement, etc., which basically have no water permeability. Vehicles and pedestrians cause a lot of inconvenience. On the other hand, stagnant water cannot seep into the ground through the surface, and the groundwater resource declines year by year. The water level drops sharply, and the soil moisture suffers great damage, endangering the ecological environment that people depend on for survival. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a preparation method of water-permeable and moisturizing pavement bricks, which is scientific and reasonable...
