|  Topic: Concrete solid brick contents mix ratio?
I'm planning to make concrete solid bricks on site approx. 4000 Nos for my house construction. The contractor will provide the small hand operated electric machine, mixer and labor, and the I need to supply the materials only. The labor for making one brick of size 12"x8"x6" is Rs 7/-. He told me that the number of bricks from one bag of cement can vary from 40 to 70 Nos based on strength requirements. So, please help me to decide the following points.1) How many first class solid bricks of size 12"x8"x6" can be produced from one bag of cement? I need only best strength for two story house with load bearing wall, and not beyond that.
2) Normally they use quarry powder not M-Sand. So, Should I use M-Sand graded for RCC work for better strength or quarry powder enough?
3) What is the ratio of mixing the contents ie. Cement, Baby metal, M-Sand/Quarry powder, water?
Thanks in advance. |

In my view your contractor giving wrong calculation. If you use Cement concrete ratio 1;2;4 than you will get 12''x8'' x6'' size bricks 20 to 22 nos If you use Ratio 1;3;6 than you will get 30 to 32 nos
Use sand which is coarse sand not fine sand and silt contents should be not more than 4%
Fine aggregate/ coarse sand consists of natural
sand, crushed stone sand or crushed gravel stone dust. It should be
hard, durable chemically inert, clean and free from organic matter, not
containing any appreciable amount of clay balls or pellets and other
harmful impurities i. e. alkaline, salt, mica, decayed vegetation, lumps
etc.
It should be passed through I. S. Sieve 4.75 MM. It should have the
finest modulus 2.50 to 3.50 and silt contents should not be more than
4%. Coarse sand should be either river sand or pit sand; or combination
of the two. It should be obtained from Badarpur Sand or Stone dust
obtained by crushing hard stones or gravel. It should also be obtained
from river bed such as Tajewala , Dadupur sand.
Note: In general the sand particle should be coarser and have minimum silt contents. The silt contents should not be more than 4%. Caution:
The quality of the sand has more impact on the strength of the structure inspite of the quantity of the cement used.
1) If there is more silt in coarse sand, the strength of cement mortar is reduced from 1 % to 30%.
2) If you take best quality coarse sand, it will give maximum strength.
