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.
Production process Description
Introduction of AAC Block Production Line:
1. Storing and supplying of raw materials of AAC blocks:
All raw materials are carried into factory by trucks, such as Fly
ash, sand or lime are gathered in specified raw materials field
waiting for use. Sacks of cement and bulk cements stored in cement
warehouse. Chemicals and aluminium powder are separately keeped in
chemical warehouse and aluminium ware hours.When used, these raw
materials are carried into workshop respectively.
2. Processing of raw materials:
Fly ash, sand or limestone is sent into ball mills by vibration
feeders and belt conveyor.Then fine powders of flyash,sand or lime
are pumped into slurry tank.
Quick lime is sent by vibrating feeder and belt conveyor into jaw
crushers to smash. Smashed lime is sent into lime silo by bucket
elevator and then is transported into ball mills by screw conveyor.
Fined materials are sent into proportion bin by screw conveyor and
bucket elevator.
3. Aerated block ingredients,stiring and casting
Flyash (or sand or stone powder )and waste slurrry are measured in
measuring tank.After the measuring and mould in their place,slurry
stirring begins. Slurry temperature should reach about 40°c.
4. Aerated block’s procuring and cutting.

Introducing the domestic and international advanced technology, the
manufactured autoclave aerated concrete (AAC)is divided into ground
flip (hydraulic flip) cutting machine, overhead flip (YiTong type
mechanical flip) cutting machine according to different cutting
process, which can produce aerated concrete block and boards with
not more than 6 M length.
Provide the complete set of production line shared by the aerated
concrete block and limesand brick, applicable for the annual output
of 100000 + 100000 cubic meters
Provide the complete set of production line of the sand aerated
concrete blocks and boards, applicable for the annual output of
50000 -200000 cubic meters
Provide the complete set of production line of fly-ash aerated
concrete blocks and boards, applicable for the annual output of
50000 -200000 cubic meters
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.
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.
