What is AAC (Autoclaved Aerated Concrete) ?
AAC block is new type & environmental construction material and widely used for industry and civil building construction. It has light ,keeping temperature , Environmental protection,can’t burn and other advantages. It has a wide prospect of market.it is the main building material in the future.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.As normally, concrete density is usually 1600-2400kg/m3,but aerated concrete are 500kg/m3,600kg/m3,700kg/m3.It has not the big grain and use silicon material (for example: fly ash,sand,stone dust and others ),through making the material small for example sand, they can be used directly if has enough degree of small (for example fly ash, Mixing calcium material lime, cement, water to a special ratio, then add the aluminum dust and the additive, then Make the aluminum dust and the special ratio have a Chemical reflect. then produce Hydrogen to make the concrete slop to expanding or swell and foam. Next put them into the curing room to concreting cutting steaming curing, At last, there will become the light brick and the porous rate is 70-80%.

Reference: cement is 42.5 Portland or 42.5 common cement
Aluminum power paste calculate to use according to 600kg/m3
Remark: the accurate batching rate is adjustable according to the raw material locally
Feature of AAC:
1. Thermal Insulation
2. Sound proof
3. Resistant of earthquake
4. Floor Space Area
5. Saving cost
6. Fire Resistant
Main Features of the AAC Block machine:
(1)simple and practial structure facilitates installation and maintenance :
(2)After tilting the blank stands vertically with the width of 600mm and the height of 1200mm,thus the cutting wire can be shorter and cutting precision can be more exactly due to that it is not easy to be broken and drifted:
(3)The vertical cutting is done by the vertical cutting device (the blank is fixed on the table)while the horizontal cross-cutting support and the cutting precision
(4)as the blank stands vertically,the grooves on both sides of the blank(with width of 600mm)can be milled at the same time when the blank is cut vertically,no groove processing device is needed
(5)The machine can process both bu
