Abstract
The invention discloses a hollow aerated brick taking phosphate tailings as a main ingredient. The hollow aerated brick is prepared from the following raw material components in parts by weight: 40-50 parts of phosphate tailings, 10-15 parts of attapulgite, 8-10 parts of plaster, 4-6 parts of cement, 0.2-0.4 part of fatty acid methanol amide, 1-1.5 parts of sodium sulfate, 0.1-0.3 part of calcium nitrate, 0.02-0.04 part of cocoalkanoylamido propyl dimethylamine crylactone, 4-6 parts of water and 2-4 parts of a composite foaming agent. The method disclosed by the invention can be used for effectively utilizing the phosphate tailings, reducing the solid pollutants and improving the waste utilization efficiency. And meanwhile, the composite foaming agent is added to prepare the hollow aerated brick, and the processed hollow aerated brick has the characteristics of a small heat transfer coefficient, good soundproof effect, light weight, high strength, corrosion resistance, and the like.
