Light weight block machinery

AAC block machine 


Brief Introduction of AAC Product

Aerated concrete brick is a light and porous building material. It is based on cement, lime, slag, fly ash, and sand and made of materials such as gas as raw material.

It has the features of being light; keeping temperature can’t be burn, good insulation and others.

It can be made into many kinds of sizes e.g. 600×200×100, 600×200×125…

They could be used in industry building and common building. As one of the earliest and most widely used materials, they are more and more popular in the world and they will replace the Clay brick completely.     


Main Features of AAC Product

A.  Light weight

Aerated concrete density is usually 400-700kg/m3, it is about 1/3 of the clay brick weight and 1/5 common concrete block weight. Using the Light brick can reduce the weight of the building and also reduce the loading of the beam of roof and pillar. You can see, it can save the material and cost, it also fight against shaking.

B.   Keeping temperature

It has many porous, the heat transition coefficient is 0.9-0.22W/ (mk), it is just about 1/4 or 1/5 of clay brick, so it is the best materials for keep the room temperature now in the world.    

C. Raw material available widely

There are many kind materials even waste material can be used to produce AAC products, for example: coal ash, sand, waste mine material, coal stone, stone dust, and other silicon materials. 

D. Saving land and energy

When you produce AAC products it use the energy (or fuel) just 11% of the clay brick Products. 

E.  The feature of Plasticity

The AAC Products has one useful advantage is the “Plasticity”. As it is has more foam inside and the weight is lighter and not so hard so it is easy to be produced in every kind shape and when it is re-assemble or re-production it will be more suitable for sawing, paring, drilling, and clinch (clench).

F. Sales Profit

AAC Products’ market profit is bigger than common bricks and cement blocks, especially the AAC Board products (Plate shape AAC Products).



AAC brick is applied widely in the world, especially in below conditions and places.

Fly Ash Aerated Concrete

Conventional fly ash aerated concrete production, uses original fly ash, lime, gypsum and other raw materials. It doesn't make use of new technology in the status quo such as pre-activation process and formula, process, technical parameters, etc. It has done a corresponding adjustment and improvement. With higher intensity compared to traditional products, its advantages are lower cost, better performance, and smaller density. Has a certain nature. Aerated concrete advantages: Aerated Concrete has been able to be rapid growing, mainly because it has many other advantages of wall materials unparalleled. (1) Light weight Aerated Concrete is the main characteristics of light weight, to win light. It dry bulk density generally 400-700kg/m3, the equivalent of clay 1 / 3 of ordinary concrete, 1 / 5, and the lightweight aggregate concrete and hollow block, hollow clay brick, compared to products such as lower. (2) Excellent thermal insulation of Aerated Concrete has a very low thermal transmittance, which have good insulation properties. It is often the thermal conductivity of 0.09-0.22w / (mk), the brick is only 1/4-1/5, 1/5-1/10 ordinary concrete. Porosity and pore its rate is about 70%, this is its thermal insulation of the main reasons. (3) Good process ability Aerated concrete without coarse aggregate, has a good process ability can be sawing, planning, drilling, nailing. When in the use of processing can be arbitrary. And the bonding material can be bonded properly. Construction to provide favorable conditions. (4) Eat a large quantity of ash, spent a high rate of profit Fly ash and other residues of the total volume ratio above 75%. Digestion can be a large number of fly ash, coal gangue, phosphorus gypsum, calcium carbide sludge and other industrial waste and is conducive to environmental pollution.
