1. Basic Introduction of AAC Block: aac production line/aac plant
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 Classification : aac 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. Advantages of AAC Block: aac block
3.1. Low weight: holes gap: 70%~80%; volume density: 400~700kg/m3,1/4 of common cement ,1/3 of fireclay brick and 1/2 air brick, able to float like wood, and to reduce building weight and low building comprehensive construction cost.
3.2. Fire resistant: well fire resistance performance without harmful gas when fired; able to resistant 700°,225mins for 100mm wall and 480mins for 200mm wall.
3.3. Noise absorption: absorbing noise with porous structure; 100mm can absorb 41 decibel.
3.4. Heat insulation: excellent heat insulation with large amount of holes and micro pores; coefficient of thermal conductivity: 0.11-0.16W/MK, 1/4-1/5 of fireclay brick.
3.5. Anti-permeability: low water-uptake for the materials consist independent pores
3.6. Anti-seismic: comparing to fireclay brick, AAC can increase 2 seismic levels.
3.7. Ecological green: no pollution during manufacture, transportation and application; protect farm land, save energy and reduce consumption.
3.8. High durability: stable strength
3.9. Easy workability: unprecedented build ability offers advantages to construct
3.10. Economic: comparing to fireclay bricks, AAC reduces 5% comprehensive construction cost
4. Performance of AAC block: aac 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.
4.1, Unit weight grade (kg/m3): 500, 600, 700, 800 (means 05,06,07,08 grade)
4.2, Compression strength grade (Mpa): A3.5, A5.0, A7.5, A10.0 (1Mpa=10kg/m2)
4.3, Drying shrinkage (mm/m): ≤ 0.8
4.4, Heat conductivity(w/m.k): 0.09-0.22
4.5,Sound-proofing performance(db): 40-47.75

6. Main Raw maerial of AAC block: aac 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.

7. AAC Production line Process: aac production line/aac plant
8.Main Production Facility of AAC: aac production line/aac plant
8.1. Prepared Facilities for Raw materials (1)Crusher: block materials like quicklime, gypsum etc which have to be crushed before using; (2) Grinding Machine: materials have to be grinded before reacting, mainly use ball mill with two types – dry and wet
8.2. Metering Facilities: wholly automatic system is usually controlled by microcomputer
8.3. Mixing and pouring Facilities: mixer is the mixing machine and also the slurry pouring machine
8.4. Cutting Machine: Autoclaved aerated concrete shapes blocks after pouring and foaming. Because of big size, blocks have to be cut into product size.
8.5. Autoclave: it is the facility for silicate product to do hydration reaction to gain physical mechanical property. The operation is related to workplace safety and energy use.
8.6. Boiler: it is used to provide autoclave and hardening room with thermal energy
8.7. Auxiliary Facilities: (1) Model frame, side plate, trolley, these facilities are used to made up pouring mould. (2) Autoclaving cart, ferry cart, hoister, these facilities are necessary to autoclaving and curing system.
