Low Maintenance Cost AAC panel machine Lightweight Wall Panel  AAC Fly Ash Slab

AAC slab/AAC panel:

1. ALC (Autoclaved Lightweight Concrete) slab, which is steel mesh reinforced, lightweight and loadbearing. AAC slab can be used as external wall panel (exterior wall panel), internal wall panel (interior wall panel), partition wall panel, flooring, roofing, fence, cladding, curtain wall and facade etc. This kind of new building material has been well used in various kinds of buildings, such as public facilities, industrial constructions, civil housing, hospitals, hotels, apartments, villas, schools, stores, supermarkets etc. The AAC slab can replace traditional precast concrete and clay bricks very well. Also the panels can easily cut, drilled, screwed when installing with fast speed due lightweight and precast.

2. Advantages of AAC panel production line

2. 1, Lightweight:The aerated concrete dry bulk density generally is 400-800kg/m3, equivalently to clay brick

 1/3, normal concrete 1/5, lower than normal light-weight aggregate concrete and hollow brick, hollow clay brick. using aerated concrete as wall material can 

lighten the building self weight, and then reduce the size of building foundation, girder and pillar etc. Structure, 

save building material and project cost, improve the building shock resistance.

Several common building material volume density (kg/m³)

 2.2, 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.

   2. 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.

    2.4, 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.

   2.5, 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.

    2.6, Anti-seismic:The same building structure, improve the two seismic than the brick level.

    2.7, Green: Manufacturing, transportation, all use the process of pollution, to protect arable land, saving energy, is one kind of a green building material.

    2.8, 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.

    2.9, Shortcut: it has good machinability, can be sawed, planed, drilled, nailed, and available appropriate as bonding of adhesive material, so create favorable conditions for building construction.

    2.10, 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.

3. Performance of AAC panel production line

   Finished AAC block is Suitable for all nonbearing wall and bearing wall of multi-story (less than six-floor),

6. AAC panel production line Process:

6.1. First,dose and match measured raw materials

6.2. After distributing,feed raw material into pouring mixer to make slurry

6.3. Through thoroughly mixing,the slurry is poured to mould

6.4. After pre-curing under a certain temperture and time,the block would reach a  certain hardness prepare for cutting

6.5. Tilting hoister would turn over 90 degree of mould

6.6. Then open the mould and separate it from block,and take the block woth side plate ti cutting cart

6.7. The blocks then be cut through the cutter firstly of two vertical sides of block

6.8. Secondly the horizontal cutting

6.9.  Finally the vertical cutting

6.10. After cutting,the block is hanged to trolly with side plate by semi-finished product hoister
