## How to Estimate No. of Bricks, Cement, and Sand in Compound Wall?

**Q) Calculate the **Quantity of Bricks, Cement**, Sand in a compound wall having Length = 30 feet, Breadth = 20 feet,**

**Height above the floor of wall = 5 feet with 5” width.**

**Height below ground = 3 feet with 10” width.**

**Bricks Size:- 190x90x90 mm**

**Step1:- Calculate volume of Wall**

**Above Ground = L x B x H = 100 x 5/12 x 5**

**= 208.3 Cub. Feet**

**Below Ground = 100 x 10/12 x 3 = 250 Cub. Feet**

**Total Volume of Wall = 458.3 Cub. Feet = 12.98 cub. meter**

**Step2:- Calculate volume of Bricks without Mortar**

**V.B = L x B x H = 0.190 x 0.09 x 0.09 = 0.001539 cub. Meter**

**Assume 10 mm thickness of mortar**

**Step3:- Calculate volume of Bricks with Mortar**

**V.B = L x B x H = 0.200 x 0.100 x 0.100 = 0.002 cub. meter**

**Step4:- Calculate no. of bricks**

**Divide volume of wall by volume of bricks with mortar**

**N.B = 12.98/0.002 = 6490 Nos.**

**Step5:- Calculate Wet volume Mortar**

**V.M = Volume of the wall – No. of Bricks x Volume of one brick without mortar**

** = 13 – 6500 x 0.001539 = 2.99 = 3 cubic meter Approx.**

**Step6 :- Calculate Dry volume of the Mortar**

**Dry Volume of mortar x 1.34 ( Add 32% to 34%)**

**= 2.99 x 1.34 = 4 cubic meter**

**Assume ratio of (Cement : Sand) = (1:4)**

**Step7:- Calculate the volume of Sand and Cement**

**V.S = Sand Ratio /(1+4) x Dry Volume**

** = 4/5 x 4 = 3.2 cub. Meter**

**V.C = Cement Ratio /(1+4) x Dry Volume**

** = 1/5 x 4 = 0.8 cub. Meter**

** Weight of cement = Volume x density of cement = 0.8 x 1440 = 1152 Kg.**

**No. of Bags of Cement = 1152/50 = 23.04 Bags of Cement ( One Bags of cement = 50 Kg.)**

**Summary**,

S.N | Description | Quantity |

1 | No.of Bricks | 6490 |

2 | Quantity of Sand | 3.2 Cub. meter |

3 | Bags of Cement | 23.04 Bags. |
