Grinding wheel ash hollow brick and production method thereof

Abstract

The invention discloses a grinding wheel ash hollow brick. The grinding wheel ash hollow brick comprises, by weight, 15-20 parts of grinding wheel ash, 30-40 parts of river silt, 25-30 parts of coal cinder, 90-105 parts of water, 20-30 parts of montmorillonite, 35-40 parts of basalt, 2-5 parts of wood chip, 1-3 parts of polystyrene beads and 2-5 parts of quicklime, and is produced through the steps of pre-activating, crushing, sealed aging, green body making, drying, sintering and the like. Industrial construction waste is fully utilized, production cost is lowered, corporate profit is increased, the production method is advanced, raw material activity and adhesiveness are improved by means of pre-activating, the raw materials are closely fused together, and the grinding wheel ash hollow brick is compact in texture, non-chalking, high in compressive strength and wear resistance, good in cracking resistance, long in service life, wide in application, high in construction adaptability and capable of being used for a long time under the condition of low temperature.

Description

technical field [0001] The invention belongs to the field of building material production, in particular to a grinding wheel ash hollow brick and a preparation method thereof. Background technique [0002] With the development of social economy, the construction industry has developed rapidly. Due to its small size, heavy weight, energy consumption, and environmental pollution, the clay solid brick is now prohibited and restricted by the state. The production and use of solid clay bricks is not allowed, Now the country is starting to promote the innovation of wall materials and the promotion of energy-saving buildings, and actively calls for the development and promotion of new building materials and products. With the introduction of preferential policies, other substitutes are now being used to burn bricks in various places. Special attention is paid to making bricks from garbage or industrial waste residues. However, the strength of bricks made from waste on the market ca...

[0002] With the development of social economy, the construction industry has developed rapidly. Due to its small size, heavy weight, energy consumption, and environmental pollution, the clay solid brick is now prohibited and restricted by the state. The production and use of solid clay bricks is not allowed, Now the country is beginning to promote the innovation of wall materials and the promotion of energy-saving buildings, and actively calls for the development and promotion of new building materials and products. With the introduction of preferential policies, other substitutes are now being used to burn bricks in various places. Special attention is paid to making bricks from garbage or industrial waste residues. However, the strength of bricks made from waste on the market cannot meet the requirements, and there are cracks and pulverization. Phenomenon, not dense, poor wear resistance, affecting the quality of the wall, wasting resources
