High Precision AAC Sand Lime Block Machine AAC Block Production Line Fly Ash
High Precision AAC (Autoclaved Aerated Concrete)
Autoclaved Aerated Concrete (AAC) is a siliceous material (sand, fly ash and silicon tailings such as waste porcelain clay, stone processing waste materials, blast furnace slag, etc.) and calcareous materials (lime, cement) as the main raw material, mixing fat gas agent (aluminum powder), by ingredients, mixing, casting, pre-curing, cutting, autoclave, curing process made of light porous silicate products, because by the hair contains a lot of gas even after the small pores, hence the name of aerated concrete
Advantages of AAC Block:
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. so, 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)
|material||aerated concrete||wood||clay brick||lime and sand brick||hollow brick||ceramsite concrete||normal concrete|
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 brick level.
7, Green: Manufacturing, transportation, all use the process of pollution, to protect arable land, saving energy, is one kind of a green building material.
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, 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.
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.
Main raw material of AAC block:
1, Sand: meet standard JC/T622-1996, technical requirements: SiO2s >65%, 0.08mm residue on sieve <20%, CaCO3<10%, So3<2%, clay<8%, no impurity.
2, Lump quick lime: meet standard JC/T621-1996, technical requirements: A-CaO>65%, slacking time 8-15min, slacking temperature >65°C, burnt lime content <8%, ash content <10%, MgO <5%.
3, Gypsum: technical requirement: Dihydrate gypsum or phosphogypsum, SO2 content >35%.
4, Aluminium powder or aluminum paste: solids content >65%,
5, Cement: meet standard GB175-92, 32.5R bulk cement.
How AAC (Autoclaved Aerated Concrete) production line working ?
- First of all, dosing of the stored raw materials
- Feed raw materials into the pouring mixer and evenly mixing
- Poured the slurry into the mould
- Static stop and pre-curing under a certain temperature, the slurry become a big block
- The big block had a certain of hardness, then be hanged for 90 degree by turning hoister
- Open the mould and de-moulding ,The big block will sit on the one side plate
- and also 8 :Horizontal cutting the big block
10. Hanging semi-product to hardening car
11. Entering autoclave
13. leaving autoclave
14. Hanging and stacking of end products
15.loading and packing
1.Production Line Design.
drawing of plant working process , drawings of land construction, drawings of power working,drawings of
driving force for working, drawings of anti-dust, drawings of water supply and drainage, and drawing of air
2.Technical Guidance of Building Factory
consultation of facility, Equipment installation guide, constitution the production preparation, etc.
3.Providing the technical information of setting up factory
part of the factory management system, all posts accountability of production line, process rules, safety rules,
setting a quota of staff and posts, pre-production tools directory, laboratory instruments, product catalogs, and
