German technology plant to produce lightweight concrete AAC blocks and Panels manufacturing process

Product Introduction

German technology plant to produce lightweight concrete AAC blocks and Panels manufacturing process


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.

AAC Classification : 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.

Product details

Material dealing process

Put the fly ash or sand into the ball mill to mill via the conveyor belt, after milling, put the slurry into the slurry storage tank by slurry pump. 


Batching, mixing and pouring process

The lime, cement will convey by conveyor to the dry powder measure scale to scale separately. The slurry convey by slurry pump then to the automatic scale;the power and slurry put into the mixer,pouring into the mould.

Curing process

After slurry pouring into the mould, put the mould box into the curing room with 50~70℃. After 2-3 hours curing,the blocks become solid

Cutting process

Using reversal crane carry the mould and block to demould on cutting cart. The cutting cart will take the block to level cutting machine,vertical cutting ,two sides cutting,and remove the top waste material.

Autoclaved

Finished cutting using semi-product crane carry to the front of autoclave grouped,hoisting machine or dragger will drag steam trolley into autoclave to steam,it need 10-12 hours.

Finished block dealing

Finished product out of autoclave,with separting machine to separate layer by layer.

Package

Using finished block carry hanger clamp the finished product to package line on wooden pallets,after  package, then by forklift transport the finished products to piled yard according to specifications to stack.

Package and delivery

1.German technology plant to produce lightweight concrete AAC blocks and Panels manufacturing proces,transport with 40HQ container.

2.The ball mill  transport with 40OT or transposrt with 40FR according the size.

3.The autoclave main body transport by car on port,and hoist  on deck of ship.

4.Cutting machine usually transport with 40FR.

5.Our package with wooden box,suitable for sea transport.

Product Advantage

                                                               The advantage of AAC block 

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.

Fireproof:Well fire resistance performance without harmful gas when fired; able to resistant 700°,225mins for 100mm wall and 480mins for 200mm wall.

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.

Noise isolation: absorbing noise with porous structure; 100mm can absorb 41 decibel.

Impermeability: low water-uptake for the materials consist independent pores

Environment protection: no pollution during manufacture, transportation and application; protect farm land, save energy and reduce consumption.

Lime(12-20%): 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.

Cement(8-10%): 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 42.5 should be first choice. While considering the cost of production Ordinary Portland Cement could also be a choice.
