The AAC blocks (Autoclaved Aerated Concrete) material was developed in 1924 in Sweden. It has become one of the most used building materials in Europe and is rapidly growing in many other countries worldwide. Aerated block machine/arc machinery/automatic block machine is available in the whole world.
Autoclaved Aerated Concrete ((AAC) blocks) is a lightweight, load-bearing, high-insulating, durable building product produced in a wide range of sizes and strengths.
Autoclaved aerated concrete (AAC Blocks) offers incredible opportunities to increase building quality and at the same time, reduce costs at the construction site. AAC is produced out of a mix of quartz sand and/or pulverized fly ash brick plant (PFA), lime, cement, gypsum/anhydrite, water and Aluminum and is hardened by steam-curing in autoclaves. As a result of its excellent properties, AAC is used in many building constructions, for example, in residential homes, commercial and industrial buildings, schools, hospitals, hotels, and many other applications.
Autoclaved aerated concrete (AAC Blocks) is actually hydrated calcium silicate. The calcium is obtained from quick lime, hydrated lime and cement. The gypsum is used as a catalyst and for optimizing the properties of AAC.
The silica is obtained from silica sand, fly ash (PFA), crushed silica rock or stone. It is possible to obtain silica as a by-product from other processes, e.g., foundry sand or burgee from glass grinding, provided the levels of alkalis or other impurities are not too high.
This product is the key equipment with a wide application in building material factories to autoclaved cure different kinds of building materials. It is also used in areas of chemical, textile, wood, metallurgy, military industry. Convenient operation, security and reliability are its advantages.
