Project Proposal of AAC block plant, annual out put 50,000-300,000m³.
About AAC blocks
- Autoclaved Aerated Concrete block is one kind of environmental Block.
- In fact AAC was perfected in the mid-1920s by the Swedish architect and inventor Dr. Johan Axel Eriksson, working with Professor Henrik Kreuger at the Royal Institute of Technology.
- Since it went into production in Sweden in 1929 in a factory in Hallabrottet and quickly became very popular.
- In the 1940s, the trademark Ytong was introduced, and was also often referred to as "blue concrete" in Sweden due to its blueish tinge.
- It used siliceous (fly ash, sand, slag) and calcareous (lime & cement) as the main raw materials, which through the process of batching, pouring, pre-curing, cutting, autoclaving, separating and packing to make into the final products.
- AAC block can be made into many kinds of bricks(for example:600×200×100,80×80×180,240×115×53,600×200×125),they could be used industry building and common building. AAC Block is the most mature technology of production and application in the worldwide nowadays.
- The product has light weight, high compressive strength, excellent thermal insulation, great acoustic insulation and high fire resistance.
- AAC has a large variety of sizes, and it is easy for nailing and milling like wood. So it is perfectly workable product.
- Raw materials include cement, lime, fly ash, gangue, river sand and aluminium powder etc. Production through batching, mixing, casting, cutting and autoclaving.
