Problems solved by technology

[0002] At present, the main raw material of load-bearing unburned bricks used in the construction industry is cement clinker, which accounts for about 70% of the total raw materials, and fly ash accounts for about 30%. The cost of this brick-making material is about 180-200 yuan / ton. And the water absorption rate is high, and antifreeze performance is poor; With fly ash as main raw material, be 89107021.4 as application number, the open technology of title " method for making unburned brick with fly ash ", fly ash accounts for about 85% of raw material amount , gypsum accounts for 2.5-4.2%, lime 12-13%, the strength of unburned bricks made according to this ratio is relatively small, and can only be used as non-load-bearing bricks, and dry finished bricks are prone to cracks and even breaks

Abstract

A non-calcined brick with low cost and hydroscopicity, high strength and antifreezing performance and no cracking is prepared from powdered coal ash as main raw material, gypsum or cement, lime, sodium sulfate, sodium chloride, triethanolamine and water through mixing and die pressing.

Description

technical field [0001] The invention relates to a load-bearing and non-load-bearing non-sintering brick made by using fly ash as the main raw material. Background technique [0002] At present, the main raw material of load-bearing unburned bricks used in the construction industry is cement clinker, which accounts for about 70% of the total raw materials, and fly ash accounts for about 30%. The cost of this brick-making material is about 180-200 yuan / ton. And the water absorption rate is high, and antifreeze performance is poor; With fly ash as main raw material, be 89107021.4 as application number, the open technology of title " method for making unburned brick with fly ash ", fly ash accounts for about 85% of raw material amount , gypsum accounts for 2.5-4.2%, lime 12-13%, the unburned bricks made according to this ratio have relatively low strength and can only be used as non-load-bearing bricks, and dry finished bricks are prone to cracks and ev...
