Automatic Autoclaved Aerated Concrete AAC Block Plant / AAC Sand Lime Block

Automatic Autoclaved Aerated Concrete AAC Block Plant ?AAC Sand Lime Block

1.Introduction

Areated concrete block (light block ) is the light and porous buidling material. It has light keeping temperature cant burn and other advantages.it can be made into many kinds of bricks for example:600×200×100,80×80×180,240×115×53,600×200×125),they could be used industry building and common building. they are more and more popular in the world.in the future, they will replace the Clay brick completely.

2.AAC block machine/lightweight block machine advantages

(1)light weight

Areated 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 or 1/5 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

(4)Cost saving
Being lightweight AAC drastically reduces the dead weight of building, resulting into reduction in steel (up to 27%) and cement (up to 20%) structural cost saving.Being 8 times the size of a clay brick, AAC wall construction involves 1/3 the joints, thus an overall mortar saving up to 66%
