Red sandstone aerated concrete and preparation method thereof
The invention belongs to the field of building materials. A red sandstone aerated concrete is characterized by being prepared from dry materials and water, and the ratio of water to material is 0.50-0.64. The dry materials include, by weight, 8%-15% of cement, 50%-75% of red sandstone, 10%-20% of lime, 1%-5% of gypsum, 0.5%-3% of metakaolin, 0%-3% of calcined hydrotalcite, 0.02%-0.15% of aluminum powder paste, 0.2%-5% of water glass and 0.05%-2% of a modifier, wherein the water glass is calculated by the solid content, and the ratio of water to material calculates the water contained in the water glass. The invention utilizes the red sandstone to prepare the energy-saving insulation wall material in line with the standard requirements, improves utilization of red sandstone, and eases the problem of shortage of river sand resources.
