Production of Lightweight Aerated Concrete Blocks density from 600 to 800 kg/m3

 

Main Components


Raw materials used are water, Portland cement, fillers (Flyash) and a Foaming agent (Aluminum powder)

- Water.
Water for concrete mixture shall of any suitable drinking water. It is preferable to water  from surface sources, unsalted, soft or medium hardness. It is also Preferred to provide the required amount of water heated to a temperature of 40-50 º C.

- Portland cement.
Virtually all of Ordinary Portland cement ( OPC 53 Grade ) suitable for the production of aerated lightweight concrete.  Preferred use of standard brands. 

Fillers.
As part of concrete mix Flyash is preferred as filler.
( Flyash is Silica rich product, which is industrial waste obtained from Thermal power plant.) Also fine silica sand, dolomite, limestone dust can be used as filler.

- Foaming agent.
Small quantity of Aluminum Powder is required for Foaming of concrete


 

Process of production

Measured quantity of water is poured in Mixer.

Measured quantity of Flyash is added in mixer with water.

Desired quantity of Cement is mixed with flyash slurry.

After the certain time of mixing, Aluminum Powder is added in Mixer.

Within 15-20 Seconds, prepared concrete slurry is poured in Molds.

After filling Molds mixer moves towards next mold for batching

In filled mold, Concrete slurry rises (just like Bread) and volume gets doubled within 30 Min.

Within 5-6 Hrs. concrete gets its initial strength and mold panels are removed.

Then this concrete “cake” is sliced in required sizes horizontally and then vertically with cutting machines

After cutting the sliced Concrete blocks are left overnight for initial hardening process.

Next day hardened Blocks are removed and stacked for curing.

Curing is done by simply spraying water on stack of blocks, just once a day for Seven Days.

After curing Blocks are ready for shipping…
