Autoclaved Aerated Concrete Block Production Line,  AAC Block Making Plant   

Brief Introduction

Autoclaved Aerated Concrete (AAC) Block is a light weight, multi-cell new construction material; the features include lower density, heat insulation, possibility, fire and acoustical resistant properties.

AAC is made from silicon material(silica sand, or recycled fly ash) and calcium material (lime, cement), mixing with foaming additive (aluminum powder),batching with, the reaction between aluminum and concrete causes microscopic hydrogen bubbles to from, expanding the concrete to about five times its original volume. It is made into the multi-cell silicate product by the processes of molding, pre-curing, cutting, evaporating and curing.

AAC block production line Capacity:

1. Sound proof

AAC wall has an excellent sound Transmission class (STC), rating of 44. Result: Virtually Soundproof Interiors

2. Thermal Insulation

It has highest thermal rating in the industry….R30! Thus provides well insulated interiors, keeping out warm air in summer and cold air in winter. AAC reduces Air conditioning cost by 30%.

3. Earthquake Resistant

Earthquake forces on structure are proportional to the weight of the building, hence AAC shows excellent resistant to earthquake forces. Regions of high seismic activity like Japan exclusively use AAC. It has been proven to withstand wind loads of category 5 tropical storms.

4. Floor Space

Area Use of thinner blocks (6" instead of 9" exterior walls) because of its excellent water barrier & insulation properties leads to an increase in floor space area between 3-5%.

5. 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%. Its automatic manufacturing process gives AAC an exceptional dimensional accuracy & smooth surfaces, eliminating need of three-coat plaster walls and allows for a final 6 mm skim coat (putty/POP).

6. Fire Resistant

Best in class fire rating of 4 hours. The melting point of AAC is over 1600 ºc, more than twice the typical temperature in a building fire of 650 ºc.

7. Pest Resistant Termites hate AAC!

Being made of inorganic minerals, it does not promote growth of molds.

8. Water Barrier

Its structure does not allow for capillary action making it impervious to water. Its water barrier properties are further enhanced by adding silicone based additives. Strength to weight ratio, higher than even M150 concrete and far exceeds the Indian Building code requirements.

9. Energy Efficient

AAC is 100% Green Building Material & is a walling material of choice in LEED certified buildings (ITC centre, the highest rated Green Building has been built using AAC). AAC is most energy & resource efficient in the sense that it uses least amount of energy & material per m³ of product.Unlike brick manufacturing process which uses previous toplayer agricultural soil, AAC uses FlyAsh (65% of its weight), thus provides the most constructive solution to the nation’s flyash utilization problem
