Product Details

Big discount Multi-functional materials uses in manufacturing acc blocks of Higih Quality

Autoclave aerated concrete block is a porous concrete product, using sand(or fly ash), cement, lime, aluminum (or aluminum paste), gypsum and othermaterials, through grinding, measuring, mixing,pouring, curing, cutting, autoclave and other processes, it belongs to silicate concrete. It is known as autoclave aerated concrete, but generally referred to AAC. It is mainly used for the frame structure building, inner wall partition, external walls orinsulation composite wall.

Advantages of AAC

light weight : The dry weight of AAC block is 400-700kg / m³, which is only 28% of clay
brick , and 20% of concrete block, reducing the weight of the building.

Convenient and fast construction:

the volume of one AAC block
equal to 18 pieces clay
bricks, can greatly improve the speed of construction. Can be easily sawing, drilling,
nailing, hanging, engraving, which makes pipelines laying, re-decoration more simple.

Exact dimensions:

Product dimensions precise,making the tolerance
of length, width and
height can be controlled within ±1.0mm. These precise size makes mortar layer thinner
and reduce the cracking problem.

Fire retardant:

AAC block is a non-combustible inorganic material
with excellent fire
resistance, fire resistance is more than 700℃. Fire resistance of AAC block wall (200mm
thick) can up to 8 hours, which is the first grade refractories.

Raw material processing

1. The cement is bulk cement, which is pneumatically transported to the cement storage bin bya bulk cement truck. The cement storage capacity considered in this design is 90t.
2. After the lime and gypsum are crushed by the jaw crusher by calculation, the elevatorenters the storage bin, is fed by electromagnetic vibration, enters the mill, and the finely mixed ash is transported by the elevator to the ash storage bin for backup.
3. The sand is transported into the slurry storage tank through ball milling and water wet milling into a slurry storage tank, and after the slurry specific gravity required for production is reached, it is pumped to a stirring pouring machine through a slurry pump.

Ingredients pouring

After the materials are ready, measure them separately, mix and stir with a stirring pouring machine,
add the metered and stirred aluminum powder suspension, stir for 30-45 seconds, and then pour into the mold.

Cutting Section.

After pouring and foaming, the green body is statically stopped to a certain hardness (about 1.2-2h), that is, cutting is performed, and the green body is lifted to a steaming cart by a marshalling spreader, and then marled into a kettle.

Autoclave

After cutting the green bodies, they can be marshalled to a certain number by driving and then enter
the autoclave for autoclaving.
