A wear-resistant water-permeable brick for squares and a preparing method thereof

Abstract

The invention discloses a wear-resistant water-permeable brick for squares and a preparing method thereof, and relates to the field of bricks for squares. The brick includes following raw materials by weight: 80-120 parts of composite Portland cement, 40-60 parts of attapulgite clay, 30-40 parts of waste or tailings, 20-30 parts of gangue, 15-25 parts of desulfurized gypsum powder, 10-20 parts of calcium stearate, 10-20 parts of coconut shell charcoal and 4-6 parts of auxiliary agents. The auxiliary agents include, by weight, 35% of a water reducer, 35% of a water repellent and 30% of a foamer. The brick is prepared by steps of material mixing and stirring, compression molding, natural curing, high-temperature drying, high-temperature calcinating, and the like. Beneficial effects of the brick and the method are that the raw materials are low in cost; the brick is energy-saving and environmentally friendly; the brick has good flexural and compressive strength, wear resistance and freezing resistance and also has certain water permeability and water-absorbing performance; when the temperature of the environment is over-high, water stored in inside holes evaporates to absorb heat, thus reducing the temperature of the environment; and an urban heat island effect can be effectively prevented when the brick is used in cities.

Description

technical field [0001] The invention relates to the field of square bricks, in particular to a wear-resistant and permeable square brick and a preparation method thereof. Background technique [0002] With the rapid development of the national economy and the continuous improvement of people's living standards, the consumption of energy is also increasing, and the problem of energy shortage is becoming more and more prominent. Therefore, energy-saving and environmentally friendly building materials are gradually being valued by people. One of the materials, it is widely used and has become a structural brick for urban roads, squares, residential areas, tourist areas and other roads. It needs to have the characteristics of anti-slip, wear-resistant, high strength, etc., and it has become a new type of building material for modern city beautification. Nowadays, ordinary square bricks are mostly made of cement and sand. Large waste, high price, poor frost resistance, poor wate...

AI Technical Summary

Problems solved by technology

It needs to have the characteristics of non-slip, wear-resistant, high strength, etc., and has become a new type of building material for modern city beautification. Nowadays, ordinary square bricks are mostly made of cement and sand. Large waste, high price, poor frost resistance, poor water absorption, and there are still many deficiencies in flexural compressive strength and wear resistance, resulting in the phenomenon of square bricks falling, pits, fractures, etc., which cannot reach the square bricks. necessary performance
