Answer / sudar

The size of the modular brick is 190 X 90 X 90
Mortar Thickness is 10mm
Assume required brickwork volume is 1 cubic metre (m3)
Volume of bricks with mortar
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

Volume of brick with mortar = 0.002 Cum (m3)

Therefore, Number of bricks required for 1 cubic metre = 1/0.002 = 500 No.s

Volume of bricks without mortar

Volume of 1 brick without mortar = 190 X 90 X 90

= 0.19 X 0.09 X 0.09

Volume of 1 brick without mortar = 0.001539 Cum (m3)

Volume of 500 bricks without mortar = 500 X 0.001539 Cum

Volume of bricks without mortar for 1 cum = 0.7695 Cum (m3)

Therefore,

Required amount of cement mortar = 1 Cum – Volume of bricks without mortar

= 1 – 0.7695

Required amount of cement mortar = 0.2305 Cum (m3) (Wet Condition)
Dry volume of a mortar = 0.2305 cum X 1.33 = 0.306565 cum
We Assume the mortar ratio is 1:6 (1 part Cement & 6 Part Sand = 7 Part)
Required amount Cement quantity in brickwork = 0.306565 X 1/7 X 1440 kg
Required amount Cement quantity = 63 Kg = 1.26 bags (50 Kg bag)
Required amount of Sand = 0.306565 X 6/7 = 0.26277 Cubic metre (m3)

Therefore, For 1 cum of brickwork, we need

500 Numbers of bricks
63 kg of cement
0.263 m3 of sand.
