Abstract

The invention discloses a high-strength aerated concrete block which is prepared from the following components in part by weight according to the conventional manufacturing process of the aerated concrete block: 28 to 32 parts of vanadiumore tailings, 5 to 10 parts of cement, 10 to 15 parts of quick lime, 5 to 10 parts of modified nanopowder, 5 to 10 parts of acetylene sludge, 3 to 5 parts of gypsum, 0.05 to 0.1 part of aluminum powder, 0.002 to 0.008 part of peregal, 0.03 to 0.08 part of calcium bicarbonate, 0.003 to 0.005 part of sodium carbonate, 0.5 to 0.8 part of calcium stearate, 0.3 to 0.5 part of zinc stearate, 0.01 to 0.03 part of sodium silicate, 0.05 to 0.1 part of hydroxypropyl methyl cellulose sodium, and proper amount of water. Through addition of nanopowder mineral powder, the volume weight of the brick is reduced, and meanwhile, the energy consumption is reduced. The high-strength aerated concrete block is good in heat insulation property and sound insulation property which are remarkably improved as compared with those of the conventional high-strength aerated concrete block. Meanwhile, the materials in a formula are optimized, so that the strength and the freezing resistance of the high-strength aerated concrete block are improved obviously.

Description

technical field [0001] The invention relates to the block field, in particular to a high-strength aerated concrete block. Background technique [0002] Air-entrained concrete is a new type of wall building material. It is unique in that it is a very lightweight new type of building wall material for thermal insulation. The air-entrained concrete technology started a hundred years ago, and my country's technology started relatively late, 40 years behind foreign countries. However, the development of my country's air-entrained concrete industry is indeed very rapid. Now the technical level of domestic air-entrained concrete technology has reached the international advanced level. [0003] The biggest advantage of aerated concrete is that it saves land resources and does not need to waste a lot of cultivated land, and its raw materials come from a wide range of sources, such as ash, slag, alum tailings and coal gangue, etc. are all raw materials for making aerated concrete.
