Embodiment Construction

[0015] An anti-corrosion aerated block, made of the following raw materials in weight (kg): waste concrete 33, quartz sand 30, pine sawdust 24, porous ceramsite 17, zirconium silicon slag 26, high sulfate-resistant portland cement 42. Water pumice 24, kyanite 22, marine dredging mud 29, desulfurization gypsum 17, carbide slag 25, hawthorn kernel powder 12, sodium polystyrene sulfonate 10, calcium hydride 4.5, water in proper amount;

[0016] The preparation method of described porous ceramsite is as follows: a, weigh titanium slag, perlite tailings, broken glass by mass ratio 7:3:2, mix uniformly, pulverize, cross 300 mesh sieves; b, by mass ratio 6:2 : 1 take fly ash, natural zeolite, allophane, mix uniformly, pulverize, cross 200 mesh sieves, add water equivalent to 3 times the amount of mixed powder weight, wet ball mill 2h, dry; c, to step Add 28% pulp waste liquid, 5% ammonium nitrite and 2.5% sodium bicarbonate equivalent to the weight of the powder prepared in step a, m...

Abstract

The invention discloses a corrosion resistant aerated building block and a making method thereof. The corrosion resistant aerated building block is made from, by weight, 23-27 parts of waste concrete, 28-36 parts of quartz sand, 16-29 parts of pine sawdust, 13-21 parts of porous ceramsite, 18-34 parts of zirconium-silicon slag, 32-46 parts of high sulfate resistance Portland cement, 17-33 parts of pumice, 14-26 parts of kyanite, 22-34 parts of marine dredged sludge, 11-22 parts of desulfurized gypsum, 19-28 parts of calcium carbide slag, 10-15 parts of hawthorn fruit seed powder, 8-12 parts of sodium polystyrene sulfonate, 3.5-5 parts of calcium hydride and a proper amount of water. The aerated building block has the advantages of strong corrosion resistance, strong resistance to acids, alkali, salts and other corrosive media, high strength, good durability, impermeability, low heat conduction coefficient, good crack resistance, safety, environmental protection and durability.

Description

technical field [0001] The invention relates to a corrosion-resistant aerated block and a preparation method thereof, belonging to the field of building materials. Background technique [0002] Aerated block is a new type of wall material that saves energy, saves soil, and makes use of waste. It is widely used in various civil and public buildings because of its advantages such as the usable area of ​​buildings. With the rapid development of my country's construction industry and the continuous improvement of people's living standards, the performance requirements of aerated blocks are getting higher and higher. However, the corrosion resistance of traditional aerated blocks is increasingly unable to meet market demand. Therefore, There is an urgent need to develop a corrosion-resistant aerated block. Contents of the invention [0003] The object of the present invention is to provide an anti-corrosion aerated block and a preparation method thereof. [0004] To achieve t...
