How much cement is required to fill up 1000 bricks?

No. of Bricks = 1000 NO’S

Brick size = 230 x 115 x 75 mm

Thickness of mortar = 10 mm (0.010 m )

Size of brick in meters = 0.230 x 0.115 x 0.075 m

Size of brick with mortar = 0.240 x 0.125 x 0.085 m

Volume of Brickwork = No of Bricks x Volume of 1 Brick with mortar

Volume of 1 Brick with mortar = 0.240 x 0.125 x 0.085
= 0.00255 m³

Volume of brickwork =1000 x 0.00255 = 2.55 m³

Volume of brick 1 brick = 0.230 x 0.115 x 0.075 = 0.00198375 m³

Volume of bricks = 1000 x 0.00198375 = 1.984 m³

Quantity of mortar = Quantity of brickwork – Volume of bricks

Quantity of mortar = 2.55 – 1.984 = 0.566 m³

Mix Ratio –> 1:5

Dry volume of mortar = Wet volume x (1+0.33) (33% of volume)

Dry Volume = 0.566 x 1.33 = 0.753 m³

Consider 5 % wastage

Dry Volume of mortar = 0.753 +( 0.753 x 0.005) = 0.791 m³

Quantity of cement:-

Quantity of Cement = {(Dry Volume of mortar x Cement ratio) / (Sum of the ratio)}

∴Quantity of cement = (0.791 x 1) /(1+5)=0.132 m³

Density of Cement = 1440 kg/m³

∴ Weight of Cement = 1440 x 0.132 = 190.1 Kg

1 bag of cement contains 50 kg of cement

∴ Number of bags = 190.1 Kg / 50 kg = 3.802 No’s (Approx. 4 bags)
