Waterproof aerated concrete block and preparation method thereof
The invention discloses a waterproof aerated concrete block and a preparation method thereof. The waterproof aerated concrete block is prepared from the following raw materials in parts by weight: 46-64 parts of desert sand, 28-36 parts of ash calcium powder, 15-20 parts of tuff, 22-28 parts of red mud, 14-21 parts of desulfurization ash, 10-15 parts of ardealite, 12-16 parts of bauxite, 4-7 parts of aluminum chloride crystal, 3-6 parts of sodium hexametaphosphate, 5-10 parts of alum, 2-3 parts of waste molasses, 3-5 parts of water glass, 1.5-2.5 parts of candelilla wax powder, 1-2 parts of methyl-ethyloxy silicone oil, 0.5-1 part of potassium perfluorooctane sulfonate and 0.7-1.3 parts of modified aluminum powder. The aerated concrete block disclosed by the invention has good waterproof property and excellent water resistance and hydration resistance and can be used for effectively solving the influence of bad conditions such as dampness and raininess on the performance of the aerated concrete block so as to prolong the service life of the aerated concrete block. The aerated concrete block also has good heat insulation property, relatively high compressive strength and broad application prospect.
