Expanded quartz sand water-permeable colored brick

Abstract

The invention relates to an expanded quartz sand water-permeable colored brick which solves the problems of poor wear resistance, poor compression resistance, low water permeability, high specific gravity and high cost of a clay kiln-fired brick and a machine-made brick for the pavement of urban sidewalks, public squares and residence communities as well as the exterior wall decoration of buildings. The brick is manufactured from expanded quartz sand disused in the production process in the firebrick production industry and is manufactured by the following steps: screening the expanded quartz sand, crushing, filtering impurities, carrying out fine grinding, mixing with cement, slag, thermal insulation beads, water, mortar hardener and pigments according to a composition ratio, uniformly blending in a blender, carrying out secondary extrusion forming in a machine-made brick forming machine, and carrying out aeration-drying to obtain final products. The invention has the advantages of scientific prescription, easy material selection, beautiful appearance of products, light weight, wear resistance, compression resistance, good water permeability and low manufacturing cost, thereby having wide market prospects.

Description

technical field [0001] The invention relates to a building material, in particular to an expanded quartz sand permeable colored brick used for urban sidewalks, public squares, open-air parking lots, residential community pavement and house exterior decoration. Background technique [0002] At present, with the continuous development of the country's economic construction and the acceleration of urbanization, the demand for building materials is increasing, and new requirements are put forward for the variety and performance of building materials. In the past, marble, machine bricks and tiles were used as materials for pedestrian walkways, public squares, residential community pavements and house exterior walls. The cost of marble mining is high, the price is expensive, the resources are limited, and it is not wear-resistant and unpressed; the production of machine bricks requires a large amount of soil as raw materials, but the area of ​​cultivated land in our country is lim...

AI Technical Summary

Problems solved by technology

The cost of marble mining is high, the price is expensive, the resources are limited, and it is not wear-resistant and unpressed; the production of machine bricks requires a large amount of soil as raw materials, but the area of ​​cultivated land in our country is limited, and it is not allowed to excavate hills and cultivated land to avoid damage. The reduction of cultivated land for grain has caused a new crisis; although tiles are beautiful as the exterior wall of a house, the applicable surface is narrow, and one brick cannot be used for multiple purposes.
