Flyash/Sand AAC Block Plant /50,000m³ to 400,000m³ annual capacity

1.1 Introduction

Autoclaved Aerated Concrete (AAC) Block, also called Light Block, used siliceous (fly ash, sand and, slag) And calcareous (lime & cement) as the main raw materials, which through the process of batching, pouring, curing, cutting, autoclaving, separating and packing to make into the final products. It is new type & environmental construction material and widely used for industry and civil building construction.

AAC Block is the most mature technology of production and application in the worldwide nowadays.
