AAC Blocks Introduction:
Shandong Dongfengshuanglong Machinery Co., Ltd. - AAC Block
AAC (autoclaved aerated concrete) block is a revolutionary building material made primarily of sand, fly ash, cement, aluminum, lime, and gypsum. Manufactured under high temperature, high pressure, and steam curing, AAC blocks offer unparalleled advantages:
- Lightweight: With a porosity of 70% to 85% and a volume density of 500-900kg/m3, AAC blocks are significantly lighter than traditional concrete, clay, and hollow bricks. This reduces building weight, lowers construction costs, and extends the building's lifespan.
- Fireproof: Composed of inorganic materials, AAC blocks exhibit excellent fire resistance and do not emit harmful gases when exposed to fire. Walls as thin as 100mm can provide up to 4 hours of fire resistance at 650 degrees.
- Sound Insulation: The unique porous structure of AAC blocks enables exceptional sound absorption, with a 100mm thick wall offering up to 41 db of sound absorption capacity.
- Insulation: The large number of pores and porous nature of AAC blocks provide excellent thermal insulation properties, with a thermal conductivity of 0.11-0.16W/MK. A 20cm thick AAC wall offers insulation equivalent to a 49cm thick solid brick wall.
- Permeability: Due to its composition of independent small pores, AAC blocks have slow moisture absorption, making them ideal for areas like bathrooms where tiles can be directly applied to the wall.
- Anti-seismic: AAC blocks enhance the seismic resistance of buildings compared to traditional brick structures.
- Green: The manufacturing and transportation processes of AAC blocks are environmentally friendly, making them a sustainable and energy-saving building material.
Main Process Flow of AAC Block Production Line:
- Dose and match measured raw materials;
- After distributing, feed raw material into pouring mixer to make slurry.
- Through thoroughly mixing, the slurry is poured to mould;
- After pre-curing under a certain temperature and time, the block would reach a certain hardness and prepare for cutting;
- Tilting hoister would turn over 90 degrees of mould;
- Then open the mould and separate it from block. And take the block with side plate to the cutting cart;
- The horizontal cutting machine cuts blocks from both sides.
- Then the vertical cutting;
- After cutting, the block is hanged to curing carts with side plate by semi-finished product hoister;
- Grouping the carts and put them into autoclaves;
- Curing the blocks under certain temperature and pressure;
- Carry the finished product out of autoclave by the winch.
- The finished product hoister take the finished product to finished blocks area;
- The side plate return back through side plate roller;
- Side plate would be organized with open mould for the next circle.
