Abstract

The invention relates to an aerated concrete building block produced by using ceramic waste and a manufacturing method thereof. The method is characterized in that: the ceramic waste, garbage burnt clinker, river sand, silicate cement, burnt lime, calcium sulfate, aluminum powder, sodium sulfate, polycarboxylate efficient water reducing agent, soap powder, borax, sodium chloride and water are used as raw materials in the method; and the method comprises the following steps of: stirring the raw materials into paste by adopting a double-shaft mixing stirrer, pouring the mixture into a die, performing standing aeration, curing and mechanical cutting and forming, conveying the formed ceramic waste aerated concrete building block to an autoclave to perform steam curing, heating the ceramic waste aerated concrete building block for 2 to 3 hours, keeping the temperature constant for 5 to 8 hours at the temperature of between 95 and 100 DEG C, and then naturally cooling the ceramic waste aerated concrete building block for 1 to 2 hours to form a ceramic waste aerated concrete building block product. The product has the advantages of light weight, high strength, no pollution, low cost and good benefit, and meets the specified requirements of energy conservation, emission reduction, development, low carbon, economy and environmental protection.

Description

technical field [0001] The present invention relates to a kind of aerated concrete block produced by ceramic waste, specifically it is the waste produced in ceramic production, the waste produced in the deep processing and polishing process of ceramic tiles and the waste slag from the bottom of the furnace after being incinerated by household garbage. The invention relates to sorting, crushing, pulverizing, drying, grinding, and the sorted powder is an aerated concrete block produced as the main raw material, which belongs to the field of waste treatment. [0002] The invention also relates to a method for manufacturing the ceramic waste aerated concrete block. Background technique [0003] Ceramics occupy a very important position in the development of my country's national economy and are an indispensable means of living in people's lives. Since the reform and opening up, my country's ceramic industry has developed rapidly. The output of ceramic floor tiles, sanitary cera...
