How to calculate the quantity of mortar in brickwork

To find the quantity of mortar in brickwork per meter cube

First, we know how many bricks have in per meter cube.

The volume of bricks per m_³ is = 500 bricks with mortar ( 20cm x 10cm x 10cm )

Where,

20x10x10 is standard L x B X D of the brick with mortar

19x9x9 is standard L x B X D of the brick without mortar

The volume of the bricks (with mortar) = 20x10x10 = 2000 cm²

= 500 x 2000

= 1000000 cm³

The volume of the bricks (without mortar) = 19x9x9 = 1539 cm²

= 500 x 1539

= 769500 cm³

Therefore, to find the volume of mortar per meter cube

= 1000000 – 769500

= 230500 cm³ ( 0.2305 m³ )

The volume of wet mortar in 1m³ is 0.2305 m³

Dry volume = wet volume x 1.33

= 0.2305x 1.33

= 0.306565~0.3 m³

The dry volume required for 1 m³ brickwork = 0.3 m³

The quantity of mortar in the brickwork of 1 m³ is 0.3 m³

Now, find the material needed for a 0.3 m³ volume of mortar.

Assume, the cement mortar ratio is 1:1 ( cement: sand )

CM 1:1 = Cement mortar 1:1 (cement: fine aggregate)

Material required for 1m3 mortar CM 1:1

1. Cement = 19.152 bags (1 bag is 50kg)
2. Fine aggregate = 1064 kg
3. Water = 479 litre

summary

The quantity of mortar in the brickwork of 1 m³ is 0.3 m³

Therefore, the Material required for 0.3 m² mortar in CM 1:1

1. Cement = 19.152 x 0.3 = 5.7456 ~ 6 bags
2. Fine aggregate = 1064 x 0.3 = 319.2 ~ 320 kg
3. Water = 478 x 0.3 = 143.4 ~ 144 liter
