Description

Measuring tank is pneumatic valve that controls the dosing in production line .
 

【Introduction】
(1). Autoclaved Aerated Concrete (AAC) block and board have become the pillar industry in construction field. China has introduced AAC technology before *0 years, our company is the earliest manufacture the RD institute of Aerated Concrete (AAC) machinery, and our technology has reached the advanced level of Aerated Concrete (AAC) machine industry.
(2) . Sales volume and comprehensive indexes of our Aerated Concrete (AAC) equipment are ahead of others in China.
(3) . Aerated concrete is characterized by the advantages of light weight, heat preservation, sound isolation, high strength, process able property and so on,
(4) . What’s more, the raw materials of AAC are abundant. Especially, it can not only make use of industrial waste residue, improve environmental pollution, and protect tillable field, but also create favorable social and economic benefits to take fly ash as the raw material of AAC block and board. Aerated concrete is the perfect wall material to replace the traditional solid clay brick.
(5). For many years, Aerated Concrete (AAC) has always accepted strong supports from the policies about reforming of wall material, tax policies and environment protection policies. Autoclaved aerated concrete (AAC) block and board have become the important part of new-type construction materials, and possess bright development future.

【Productive Process of Aerated Concrete】
（1）.Production Process of Aerated Concrete According to the category and quality of raw material, and the features of equipment, the aerated concrete can be manufactured in different processes. Generally, add water to ash, silica sand or slag and crush them into slurry;
 (2) . Then add powdery lime, cement of right amount, plaster, vesicant, foam stabilizer, and mix and pour it to mould frame;
（3）.After curing, foaming and hardening, cut it into blocks and boards in different specifications;
 (4).Finally, transport it into pressure steamer with steam-curing cart, and get the light cellular concrete after steam-curing with high temperature and pressure.
