AAC/50000-300000 m3/year aac lightweight block-Factory direct

1. Basic Introduction of AAC lightweight block :

Main raw materials of AAC are siliceous material (sand, fly ash and Silicon tailings) and Calcium materials (lime and cement) mixed with foaming agent (aluminum powder). It is the product of light porous silicate through the following processes: batching, mixing, pouring, hardening, cutting, autoclaving and curing etc. Because of large amount of well-distributed tiny pores after foaming, it is named autoclaved aerated concrete.

2. AAC lightweight block :

In general, it can be classified according to the types of raw materials,   manufacture process and functions. Based on the shape of AAC products, it can be divided   into: AAC blocks and AAC panels. It is a revolutionary material offering an unique combination of high durability and strength, low weight, excellent heat insulation, fire resistant, noise absorption, unprecedented build ability and superior ecological green features. In China, AAC is one of the light wall materials which was popularized and applied at the earliest and the most widely.

3. Performance of AAC lightweight block :

Finished AAC block is Suitable for all nonbearing wall and bearing wall of multi-story (less than six-floor), nonbearing wall internal parting wall, thermal insulation rooms front panel, floorslab.

     1) Unit weight grade (kg/m3): 500, 600, 700, 800 (means 05,06,07,08 grade)

     2) Compression strength grade (Mpa): A3.5, A5.0, A7.5, A10.0 (1Mpa=10kg/m2)

     3) Drying shrinkage (mm/m):  ≤ 0.8

     4)Heat conductivity(w/m.k): 0.09-0.22

     5)Sound-proofing performance(db): 40-47.75

    Conforming with China national standards GB11968-1997 (the latest AAC block national standard)

4. Normal size of AAC lightweight block :

   Length (mm): 600

   Width (mm): 75, 100, 125, 150, 175, 200, 250 

                              60, 120, 180, 240

   Height (mm): 200, 240, 250, 300

   Remarks: the size can be customized

5. Main Raw maerial of AAC lightweight block :

Abundant raw materials can be used to produce AAC, especially flyash which is the ideal kind of wall material to take the place

of fireclay bricks, not only can it make use of industrial solid waste, curb environmental pollution, protect farm land, but also can create benefits to social effect and economic effect. Over these years, it has been greatly supported by national wall-revolution policy, tax policy and environmental policy.

1). Fly ash: the core raw material of AAC product; the main resource of silica-aluminum components; correspond with JC409-91

2)  Cement: the strength of fly ash AAC product mainly depends on cement which provides calcium materials. The cement suits to the AAC product lying on its type and label. Ordinary Portland Cement 52.5 should be first choice. While considering the cost of production Ordinary Portland Cement could also be a choice.

3) Lime: one of the main raw materials of fly ash AAC; the main effect is to provide efficient calcium oxide with cooperation of cement making calcium oxide react with SiO2,Al2O3 in hot water then to produce calcium silicate hydrate. Therefore, lime is also the main resource of strength. Effective calcium oxide of lime should not less than 65%, over 80% is perfect and should accord with JC/T621-1996.

4) Gypsum: Gypsum is the foaming regulator in AAC which dispels quicklime and postpones slurry’s densification.

5) Foaming Agent: There must be foaming materials working as foaming agent making air holes to form porous structure.

6) Foam Stability: After foaming, the thin bubbles are easily breakup disturbed by other things affecting AAC quality.
