Brief introduction

Areated concrete brick (light brick ) is the light and porous buidling material. It has light weight 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.

AAC block production line is produced out of a mix of cement, lime, fly ash, gangue, river sand and aluminium powder ect., through batching, mixing, casting ,cuttimg and autoclaving. AAC has the advantages of extremely light weight, high compressive strength, excellent thermal insulation, great scousitc insulation and high fire resistance. AAC can be produced in a large variety of sizes, from stand blocks to large reinforced panels, and it can be cut, sawn ,drilled ,nailed and milled like wood, making it an extremely workable product, AAC is environment-friendly and new building material.

Advantages of the AAC block application

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 winters. 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 top layer agricultural soil, AAC uses Fly Ash (65% of its weight), thus provides the most constructive solution to the nation's fly ash utilization problem.

Hongfa is a complete solution supplier and a complete set of equipment production line supplier 

Hongfa Autoclaved Aerated Concrete(AAC) Block Production Line /gas concrete block machine layout 

Hongfa AAC production line includes:raw material preparation → mixing & pouring → molding → curing & cutting → steam generating system → autoclaving → finished products upload & packing

I .Raw material preparation for AAC plant 

1. Milling sand (fly ash no need mill) and to make slurry

2. Lime:crushing - milling (or to buy lime power directly)

3. Gypsum : to mill with sand or input with fly ash then to make slurry directly

II .Dry and wet ball mill for lime and sand 
 

III . Slurry  batching

The prepared and stored raw materials to be used are metered ,adjusted for temperature and concentration,and a small amount of dosing materials are metered on-site,and then fed to the stirring equipment in turn according to the process requirements .
 

IIII. Pouring 

In this process ,the materials that are put into the mixer after the previous batching prosess are measured and adjusted if necessary,and the materials that meet the time,temperature,and consistency requirements of the process are made,then pouring into the mold.the pouring process is an important process that can form a good pore structure,and it constitutes the core link of aerated production as the batching process
 

Packing: Naked packing or stretch film packing or according to customers' requirements
Delivery time: Within 30 days after receipt of deposit and moulds confirmation from buyer
