In this article, we will learn to calculate the Cost of 1CFT Brickwork and the number of Bricks, Cement, sand required for a 1 CFT Brick Wall. The brick wall consists of has a mortar joint with a cement-sand ratio of 1:6.

**Cost of 1 CFT Brickwork**

Size of Bricks (found in Field) = **9″ x 4.5″ x 3″.**

Volume of Brickwork = 1 CFT

Volume of One Brick without mortar = 0.75′ x 0.375′ x 0.25′ = 0.07 CFT.

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

= 1/ (= 0.07) = 15 Nos.

Add 0.39″ thickness mortar joint, Hence;

Size of Bricks = 9.39″ x 4.89″ x 3.39″.

Volume of one Bricks with mortar = 0.7825′ x 0.4075′ x 0.2825′ = 0.09 CFT.

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

= 1/ (0.09) = 12 Nos.

Hence. Numbers of Bricks have reduced from 15 to 12 due to the presence of Mortar.

#### Mortar Calculation for 1CFT Brickwork

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

= 1 – (0.07 x 12) = 0.16 CFT.

**Therefore we need 12 Bricks and 0.16 CFT Cement Mortar for 1 CFT Brickwork.**

Now we also have to find how many bags of cement and how much quantity of sand is needed for 0.16 CFT of Mortar.

Wet volume of Cement Mortar = 0.16 CFT.

Dry Volume of Mortar = 0.16 x 1.33 = 0.2128 CFT.

C: S Ratio = 1:6.

**Cement Calculation**

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

= (0.2128 x 1) (1+6) = 0.2128 /7 = 0.0304 CFT.

Density of Cement ing KG/CFT = 40.77626 Kg/CFT.

Cement in Kilogram = 0.0304 x 40.77626 Kg/CFT. = 1.24 kg

#### Sand Calculation

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

= (0.2128 x 6) (1+6) = 1.2768/7 = 0.1824 CFT

In Short for 1 CFT Brickwork we need;

**Bricks = 12 Nos.****Cement = 1.24 kg****Sand = = 0.1824 CFT**

**Material Cost of 1CFT Brickwork**

Cost of Cement Bag = NPR 16 per kg of cement.

Cost of Sand = NPR 55 per CFT

Bricks = NPR 13 per Number of Bricks

**For the Cost of 1CFT Brickwork, Cost of Material shall be.**

**Cement = 1.24 kg @ NPR 16 = 19.84****Sand = 0.1824 CFT @ 55 = 10.032****Bricks = 12 Bricks @ 13 = 156.**

**Total Cost Of Material for 1 CFT Brickwork = 19.84 + 10.032 + 156 = NPR 185.872.**
