AAC BLOCKS

We are pleased to introduce ourselves as ‘KAMLESH GREENCRETE PVT LTD’, engaged in manufacturing

of AAC (Autoclaved Aerated Concrete) light weight blocks. We have set up a state of art AAC manufacturing

plant at Gummidipoondi, Chennai, Tamilnadu with a production capacity of 15,000 cubic meter per month.

These are fabricated at our site using finest quality of Fly ash (Carbon less), to ensure their durability, reliability

and eco-friendliness. Owing to light in weight, good compressive strength, low water absorption, good thermal

properties, AAC blocks find huge application in construction industry. Manufactured as per the Construction

industry norms.

Sizes Available:

600mm x 200mm x 200mm (8”)

600mm x 200mm x 150mm (6”)

600mm x 200mm x 100mm (4”)

KAMCRETE AAC Blocks are more competitive with other conventional bricks in pricing and offers significant

saving for finished structures. Savings in construction cost can be as much as 18% when using AAC Blocks, as

compared to other conventional bricks, after taking into consideration the resulting savings in gravel, cement,

steel, labor, structure, foundation etc.

Consistent quality of KAMCRETE AAC Blocks has brought ample of advantages to the modern construction.

ISI MARK & NORMS

Light weight

Being light weight, KAMCRETE AAC Blocks reduces the load on foundation and structures resulting in

substantial saving in steel and cement.

Lower water absorption

This closed cell structure of KAMCRETE AAC Blocks reduces water absorption, So, no more damp spots

on the walls.

Thermal insulation

Superior thermal insulation of KAMCRETE AAC Blocks makes it comfortable for the occupants. It results

in lower electricity cost due to reduced air- conditioning loads.

Lower labour and material costs

Decrease in number of joints and accurate dimensions of blocks result in reduced cement mortar, plastering

and labour.

Increased carpet area

Optimum width results in increased carpet area when compared to brick walls.

Quick and easy assembly

Being larger in size, KAMCRETE AAC Blocks speeds up the construction process and makes it simpler.

Superior sound insulation

Acoustic properties of KAMCRETE AAC Blocks are superior compared to other walling materials.

Ecological stability

KAMCRETE AAC Blocks are eco-friendly Blocks. No Green house gases are emitted during the

manufacturing process. Valuable top soil is also not consumed.

Superior fire safety

KAMCRETE AAC Blocks offer superior fire safety.

Reliability and quality consistency

State of the art ensures that KAMCRETE AAC Blocks have consistent dimensions & strength.

Availability through all seasons

KAMCRETE AAC Blocks is available all year round; even during monsoons when the availability of the

fire clay bricks is not consistent

Ease of handling

Lower weight ensures easy handling. Offers superior nailability and chase cutting features as compared to

hollow blocks and concrete blocks.

Any finish on walls

KAMCRETE AAC Blocks allow us to opt for any finish on walls – external plastering, cladding, tiling,

internal tiling, dry lining, spray plaster or anything of your choice.

Sailent Features:-

Reduces Construction Cost,

No Burning of Fossil Fuel (Coal),

No Emission of Carbon Di-Oxide (Co2),

Steam cured Cement Blended Blocks,

No Top Soil Cutting which Saves Precious Land.

Use of Fly ash based AAC Blocks are made Mandatory by Government of India for all Construction Activities by

Government, Semi Government Organizations, Public and Private Sector.

Green building Comparison between (AAC) blocks and Clay bricks

S.No Parameter AAC Blocks Clay Bricks

1 Soil Consumption Uses fly ash which is a thermal power

plant waste product & thus no consumption of top soil

One sq ft of carpet area with clay brick walling will

consume 25.5 kg of top soil

2 Fuel Consumption One sq ft of carpet area with AAC blocks will consume 1 kg of coal

One sq ft of carpet area with clay bricks will consume 8

kg of coal

3 CO2 Emission One sq ft of carpet area will emit 2.2 kg of CO2

One sq ft of carpet area will emit 17.6 kg of CO2

4 Labour Organized sector with proper HR practices

Unorganized sector with rampant use of child labour

5 Production Facility State-of-the-art factory facility Unhealthy working conditions due to toxic gases

6 Tax Contribution Contributes to government taxes in form of Central Excise, VAT and Octroi
