2.AAC Block Introduction:
Autoclaved Aerated Concrete (AAC) Block, also called Light Block, used siliceous (fly ash, sand, slag) and calcareous (lime & cement) as the main raw materials, which through the process of batching, pouring, 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.
3.AAC Block Advantages & Features:
(1) Lightweight:300~700kg/m3
(2)High Intensity:3.5~10.0Mpa
(3)Good Thermal Insulation Property:0.1~0.20W/(m · k)
(4)Keeping Temperature, Heat preservation, Fireproof
(5)Good Sound Insulation:47.25db;
(6)Earthquake Proof
(7)Good operating
(8)Conveniently Mechanized Construction
4.Main Process Flow of AAC Machine:
(1)Raw material:Store the flyash (tailings etc), lime and gypsum after milling to the needed fineness (200 mesh);
(2)Mixing the fly-ash, cement, lime, gypsum and water in the pot after batching.
(3)Promote the slurry temperature to 40to50 degree by steam, and mill with aluminum powder for 1min.
(4)Pour the slurry into the mould, and still in the curing room for frothing in 2-2.5h.
(5)Cut it in to needed size by the cutter after the slurry approach the cutting
Intensity, and place the block on the trolley.
(6)Autoclaved curing after the trolley enter into the autoclave (vacuum, rise the pressure,
Keep the pressure, reduce the pressure),keeping the constant pressure 1.2MPa.
The whole process needs about 8 hours.
5.The normal size of AAC Block:
Length (mm):600
Width (mm):75, 100, 125, 150, 175, 200, 250
Height (mm):200, 240, 250, 300
