Advantages of the aac block
1. Lightweight: Porosity achieve 70% to 85%, volume density is generally 500 ~
900kg/m3, as 1/5 of general concrete the 1/4of clay, the 1/3 of
hollow brick, and similar with wood can float in water. It can
reduce building weight, reduction in the cost of integrated
2. Fireproof: Most of the major raw materials is inorganic materials, so it has
good fire resistance, and do not emit harmful gases when meet fire.
Fire 650 degrees, as a refractory material, the thick up of 90mm
walls can reach to 245 minutes fire resistance, 300mm thick up wall
can reach to 520 minutes fire resistance.
3. Sound insulation: Due to a unique porous structure, so it has a sound absorption
capacity. The sound absorption capacity can reach of 10mm thick
wall up to 41 db.
4. Insulation: As the material inside has a large numbers of the pores and
porous, which has a good thermal insulation properties. The Thermal
conductivity is 0.11-0.16W/MK, as 1/4-1/5 of brick. Typically, the
insulation effect of 20cm thick aerated concrete wall is equivalent
to 49cm thick solid brick walls ordinary.
5. Permeability: Result of material by the composition of many independent small
pores, the moisture absorption is slow, in the volume of absorbent
is 5 times of clay saturation do. When used in the bathroom, the
wall can be treated to interface directly paste tiles.
6. Anti-seismic: The same building structure, improve the two seismic than the
7. Green: Manufacturing, transportation, all use the process of pollution,
to protect arable land, saving energy, is one kind of a green
8. Durability: material strength is stability, in the specimens tested after one
year of atmospheric exposure; the intensity increased by 25%, and
remained stable after ten years.
9. Economies: An integrated lower cost than using more than 5% of solid clay
bricks, and can increase the usable area, greatly enhance the
utilization of floor space.
SANKON Building Materials Technology Co. is a one stop solutions
provider for autoclaved aerated concrete (AAC) production equipment
including complete AAC production lines. We employ a team of
experts with more than 20 years of industry experience to drive our
innovative efforts and create highly efficient building material
production equipment. Using highly automated production machinery,
SANKON is able to produce more than 9 thousand tons of equipment
each year to satisfy our customers all over the world. Contact us
today to learn more about our outstanding AAC production machinery.
Process flow of AAC production line:
1. Raw materials processing
Put the fly ash or sand into the ball mill to mill via the conveyor
belt, after milling, put the slurry into the slurry storage
tank by slurry pump.
2. Batching, mixing and casting
The lime, cement will convey by conveyor to the dry powder measure
scale to scale separately. The slurry convey by slurry pump
then to the automatic scale;the power and slurry put into the
mixer,pouring into the mould.
After slurry pouring into the mould, put the mould box into the
curing room with 50～70℃. After 2-3 hours curing,the blocks become
Using reversal crane carry the mould and block to demould on
cutting cart. The cutting cart will take the block to level cutting
machine,vertical cutting ,two sides cutting,and remove the top
Finished cutting using semi-product crane carry to the front of
autoclavegrouped,hoisting machine or dragger will drag steam
trolley into autoclave to steam,it need 10-12 hours.
6. Finished block dealing
Finished product out of autoclave,with separting machine to
separate layer by layer.
Using finished block carry hanger clamp the finished product to
package line on wooden pallets,after package, then by forklift
transport the finished products to piled yard according to
specifications to stack.
