Environmentally friendly aerated brick containing various wastes
The invention discloses an environmentally friendly aerated brick containing various wastes. The environmentally friendly aerated brick containing various wastes is made from, by weight, 5-10 parts of volcanic rock powder, 2-5 parts of rice flour, 1-2 parts of carboxymethylcellulose sodium, 3-5 parts of calcium lignosulfonate, 0.5-2 parts of nanometer titanium dioxide, 0.2-0.8 parts of polyethylene wax, 0.5-2 parts of azodicarbonamide, 0.3-0.5 parts of sodium citrate, 1-3 parts of hydrogen peroxide with the concentration of 20-30%, 30-35 parts of modified waste compounding powder, 10-15 parts of cement, 6-8 parts of gypsum and a proper amount of water. The environmentally friendly aerated brick has the advantages of non-sintering, low energy consumption and no waste gas discharge, solves the problems of low construction waste processing efficiency, unstable product performances and poor market application in previous waste wall brick technologies, and accords with national energy saving and emission reduction policies. The compressive strength, the flexural strength, the frost resistance and the drying shrinkage of the standard aerated brick produced by using the wastes respectively reach national standards.
