Process of Manufacture of CLC Bricks

Machines we are using :

1. Mixer (Ribbon Type)
2. Conveyor
3. Water Pump
4. Foam Generator
5. Digital weighing system
6. Compressor
7. Control Panel
8. Trollies to carry slurry
9. Water tank 2000 ltrs capacity
10. Foam Tank 500 ltres capacity
11. Platform Trollies
12. Molds

Materials :

1. Cement
2. Fly Ash
3. Protein Foam (Veg)
4. Water
5. Demoulding oil

Process : 

To manufacture one m3 CLC Bricks, first we fill the water as per requirement with pump from water tank, Later we run the conveyor and conveyor belt drops 500 kgs of Fly ash into the Mixer. Flyash and Mixer will be started simultaneously. We drop the 5 bags i.e., 250 kgs of 53 grade OPC cement in to the Mixer. Later 1.2 kgs of foaming Agent diluted with 30 litres of water will be added and mixed thoroughly. Air bubbles thoroughly mixes in cement and flyash slurry. At this point the one litre slurry taken out from Mixer and weighed for density. If it shows the required density, the slurry will be drained into trollies and these trollies transports slurry to the place where molds kept. This CLC cement slurry poured into molds. The outer frame of the molds removed after 18 to 24 hours and the separation plates removed after 48 afters. Then the finished CLC Bricks removed to curing area and curing will be done for 28 days. From 29th day onwards our CLC Bricks ready for sale. We are using 600mm x 200mm x 100/150/200mm molds.

CLC Bricks comparison with Red Bricks

How we compare CLC bricks with red bricks when we meet customer ?

If we take One CLC Brick with the size of 6*8*24, which equals 10.6 Red bricks.
One cubic meter area covers 55 CLC Bricks of above size or 560 Red Bricks.

The market price now for CLC Bricks is 3200 Rs per each cubic meter and Red bricks market price starts from minimum Rs. 2440 to 3500 and it varies depend upon quality and city to city.

So the question comes from customer immediately is why I spend more money for CLC bricks?

Here is the answer
Take this example:
1 unit wall brick construction with CLC and Red brick

1) clc bricks for 1 unit wall required around 55 bricks
2) red bricks for 1 unit wall comes around 560 bricks

3) quantity of cement and sand requires for mortar 1 unit wall with CLC
cement : 1 bag cement
sand : 4 bags sand
price : 210 Rs for cement
140 Rs for sand
----------------------------------
Total 350 Rs/-
-----------------------------------
4) quantity of cement and sand requires for mortar 1 unit wall with Red bricks
cement : 2.5 bag cement
sand : 10 bag sand
price : 525 Rs cement
350 Rs for sand
----------------------------------
Total 875 Rs /-
-----------------------------------
5) Plastering for wall constructed with CLC Bricks:
half inch plastering is Enough
Cement : 1.5 bag cement
Sand : 6 bag sand
Price : 315 Rs for cement
210 Rs for sand
----------------------------------
Total 525 Rs/-
-----------------------------------
6) Plastering for wall constructed with Red bricks:
1.5 inches plastering is needed
Cement : 3.5 bag cement
Sand : 14 bag sand
Price : 435 Rs for cement
490 Rs for sand
----------------------------------
Total 925 Rs/-
-----------------------------------

Total cost for plastering and motor joints For clc bricks.
350 + 525 = 875 Rs. Plus cost of CLC 3200 i.e. total 4075 per cubic meter.

Total cost for plastering and motor joints For red bricks.
875 + 925 = 1800 Rs. Plus cost of Red bricks 2500 i.e.,total 4300 per cubic meter.

So at the end of the 1 unit wall construction the price we are spending for red bricks is more than wall made with CLC bricks, apart from that contractor can construct the building less time than red brick construction.

Customer can happy with the advantages mentioned earlier post.

Note : The above calculation we are giving for construction a building with CLC its varies cities and cities and place to place.
