Abstract

The invention relates to an aerated concrete block with a good anticorrosion property, and a preparation method thereof. The aerated concrete block with the good anticorrosion property is prepared by the following raw materials by weight: 18-22 parts of cement, 16-18 parts of quicklime, 8-15 parts of gypsum, 0.3-0.4 part of aluminum powder, 8-12 parts of propylene glycol, 40-50 parts of quartz sand, 10-14 parts of block slag, 3-4 parts of urotropine, 2-3 parts of sodium benzoate, 3-5 parts of sodium persulfate, 3-5 parts of oil residues, 3-5 parts of epoxidized soybean oil, 5-7 parts of sodium bicarbonate and 15-20 parts of rice bran. The raw materials of the urotropine, sodium benzoate and the like are used, so that the aerated concrete block has relatively good anticorrosion effect, and the service life of the block in an acid and big alkaline environment can be prolonged.

Description

technical field [0001] The invention belongs to a building material technology, in particular to a concrete block and a preparation method thereof. Background technique [0002] As a new type of wall material, air-entrained concrete is a low-energy, environmentally-friendly new building material, which belongs to the building materials promoted by the state. However, because ordinary air-entrained concrete is made of cement, fly ash, quicklime, gypsum, etc. Large shrinkage value, low strength, water seepage, no corrosion resistance, poor heat insulation, single source of material, etc. Therefore, further research on aerated concrete block technology is urgently needed to further meet market requirements. Contents of the invention [0003] The object of the present invention is to provide an aerated concrete block with good corrosion resistance and a preparation method thereof, so as to solve the problem of poor corrosion resistance of the current aerated concrete block. ...
