Corrosion resistant aerated building block and making method thereof

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.
