Cost of 1 Cum Brickwork: Bricks Cement and Sand Price

In this article, we will learn to calculate the number of Bricks, Cement, sand, and also the cost required for 1 Cum Brickwork. The brick wall consists of a mortar joint with a cement-sand ratio of 1:6. The Field Bricks of Size 230 mm x 114 mm x 76 mm.

Cost of 1Cum Brickwork

First we need to Know how many number of bricks, cement and Sand required for 1 cum brickwork. Let find it.

Volume of Brickwork = 1 cum.

Size of Bricks = 230 mm x 114 mm x 76 mm

Volume of One Brick without mortar = 0.23 m x 0.114 m x 0.076 m = 0.00199272 cum.

Number of Bricks Required without Mortar = (Volume of Brick Work)/ (Volume of One Brick without Mortar)

                                                                                    = 1/ (0.00199272) = 502 Nos.

Add 10 mm thickness mortar joint, Hence

Size of Bricks = 240 mm x 124 mm x 86 mm.

Volume of one Bricks with mortar = 0.24 m x 0.124 m x 0.086 m = 0.00255936 cum

Number of Bricks Required with Mortar = (Volume of Brick Work)/ (Volume of One Brick with Mortar)

                                                                                    = 1/ (0.00255936) = 391 Nos.

Hence. Numbers of Bricks have reduced from 502 to 391 due to the presence of Mortar.

Quantity of Mortar Volume = Volume of Brickwork – (Volume of Brick without mortar x Number of brick required with mortar)

                                                       = 1 – (0.00199272 x 391) = 0.22084648 cum

Therefore we need 391 Bricks and 0.23 cum Cement Mortar for 1 Cum Brickwork.

Now we also have to find how much cement and how much quantity of sand is needed for 0.23 cum of Mortar.

Wet volume of Cement Mortar = 0.23 cum.

Dry Volume of Mortar = 0.23 x 1.33 = 0.3059 cum.

C: S Ratio = 1:6.

Cement Calculation For 1 Cum Brickwork

Cement in Cum = (Volume of Mortar x Ratio of Cement) / (Sum of Ratio)

                = (0.3059 x 1) (1+6) = 0.3059/7 = 0.0437 m3

Cement in Kilogram = 0.0437 x 1440 = 62.928 Kg.

Cement in Bag = 62.928 / 50 = 1.26 Bags.

Sand Calculation For 1 Cum Brickwork

Sand in cum = (Volume of Mortar x Ratio of sand) / (Sum of Ratio)

                = (0.3059 x 6) (1+6) = 0.3059/7 = 0.2622 m3

In Short for 1 Cum Brickwork we need;

Bricks = 391 Nos.

Cement = 1.26 Bags (= 2 Bags)

Sand = 0.2622 cum.

Cost of Material For 1 Cum Brickwork

Price of Cement Bag = NPR 800 per bag of 50 Kg.

Cost of Sand = NPR 55 per CFT or 55 x 35.29 = NPR 1940.95 per Cum.

Bricks = NPR 13 per Number of Bricks

For 1 cum Brickwork, Cost of Material shall be.

Cement Bar = 2 Bags @ 800 = 1600

Sand = 0.2622 cum @ 1640.95 = 509

Bricks = 391 Bricks @ 13 = 5083.

Total Cost of Material for 1 Cum Brickwork = 1600 + 509 + 5083 = NPR 7192.

Total Cost of Material for 1 Cft Brickwork = 7192/35.314 = NPR 203.65
