1. introduction of China AAC Blocks Dongyue Machinery Group :
Areated concrete block (light block ) is the light and porous buidling materi
al. It has light keeping temperature cant burn and other advantages.it can be
made into many kinds of bricks for example:600×200×100,80×80×180,240×1
15×53,600×200×125),they could be used industry building and common buil
ding.they are more and more popular in the world.in the future,they will repl
ace the Clay brick completely.
Areated concrete common conception Common concrete density is
usually 1600-2400kg/m3,but Areated concrete are 500kg/m3,600kg/m3,700kg/m3.It has
not the big grain,main use silicon material (for example:coal ash,sand,
stone dust and others ),through making the material small for example
sand,they can be used directly if has enough degree of small (for example
coal ash.Mixing calcium material lime cement water to a special slop,then
add the aluminum dust and the additive.Make the aluminum dust and the
special slop have a Chemical reflect.then produce Hydrogen to make the
concrete slop to expanding or swell,foam.Next,put them into the curing
room to concreting cutting steaming curing,last,there will bacome the
light brick,the porous rate is 70-80%.

2.AAC block advantages

(1)light weight
Aerated concrete density is usually 400-700kg/m3,(according the market in produce ),same as 1/3 of clay brick and 1/5
common concrete.So use the Light brick can reduce the weight of the
build more,and also reduce the beam of roof and pillar press best.then
you can see,it can save the material and cost,it also fighting shaking.
(2) keeping temperature
It has many are porous,the delivery hearting coefficient is 0.9-0.22W/(mk),the same as 1/4 or1/5 of clay brick,so it is best materials now
in the world.There are many kinds material,have lowest waste.
(3)High Strength
High pressure steam-curing autoclaving process gives AAC unmatchable strength to weight
ratio, higher than even M150 concrete and far exceeds the Indian Building
code requirements
3.AAC block Market Analysis
AAC is becoming more and more popular around the world, from western
countries and then to developing countries. Below Properties make AAC
have unmatchable property, especially for high buildings:
1) Extreme Light Weight
2) Large Variety of Sizes
3) High Fire Resistant<
4) Excellent Thermal Insulation
5) Great Sound Insulation
6) Moisture Protection
7) Termite Resistant
8) High Workability and Easy Processing
