Brickwork cement and sand calculation
The Brick masonry calculation comprises brick units bonded together with mortar. The strength of brick masonry depends upon the quality of brick, the quality of artillery, the mortar ratio, and the method of the bonding tool.
From this Brickwork calculation, you can identify to require the number of bricks, require the cement, and sand for brickwork construction or also calculate how much cement and sand require for 100 bricks.
Here, you can learn how to calculate brick quantity, and the quantity of cement and Sand required for brickwork construction.
- Bricks used in the construction are available in different sizes based on the location for our present study let us take a standard size of modular brick is
190 X 90 X 90 mm - Assume Mortar thickness as 10 mm
- Cement mortar ratio 1:6
- The calculation for the Brickwork volume 1cum (1 cubic meter) – Volume of your brickwork
Step 1
The volume of 1 brick with mortar
= 200 X 100 X 100 (10 mm mortar thickness on all sides)
= 0.2 X 0.1 X 0.1
= 0.002 Cum (m3)
Step 2
The volume of 1 brick without mortar
= 190×90 × 90
= 0.19 × 0.09 × 0.09 (converting to the meter)
= 0.001539 Cum (m3)
Step 3
The volume of 500 bricks without mortar
= 500 × 0.001539 Cum
= 0.7695 Cum (m3)
Step 4
The required amount of cement mortar
= 1 Cum – Volume of bricks without mortar
= 1 – 0.76
= 0.2305 Cum (m3) (Wet Condition)
Step 5
The Calculated volume is in a wet condition which means we need 0.2305 cum cement mortar in mixed condition (after mixing water).
- To find the dry volume, we need to multiply 33 % as the bulkage of sand.
Dry volume of a mortar
= 0.2305 cum × 1.3
= 0.306565 cum
The mortar Ratio is 1:6
1 part cement and 6 part sand, total part 1+6 =7
Density of cement = 1440 kg,
To calculate the cement quantity
1= cement part
7= total
The required amount of Cement quantity in brickwork
= 0.306565 × 1/7 × 1440 kg
= 63 Kg
= 1.26 bags
Approximately 1.26 bags if the bag is 50 Kg
- 6 = Portion of sand on the total amount
- 7 = total amount
The required amount of Sand = 0.306565 × 6/7 = 0.26277 Cubic meter
For 1 Cubic meter of Brickwork,
We require,
1,500 Bricks
2.63 Kg Cement
3.0.263 cum sand.
