**Calculation of bricks- how to calculate the number of bricks in a wall,****calculation of bricks in a wall,**we should need estimate of essential building material for new projects, we should need estimate of bricks sand aggregates and Cements and steel.

Every civil engineer try to calculate and estimate calculation of bricks in a wall and how to calculate number of bricks in a wall.

Calculation of bricks in very simple and easy method for estimate of new building projects. We know that bricks are are very in in size according to different nation local manufacturing but in this topics we should consider IS standard size of bricks.

**procedure for calculation of bricks in wall**

**1) volume of wall which are built**

**2) volume of standard size brick**

**3) details of volume of opening in the wall**

**4) volume of wastage of bricks**

**■1) volume of wall :**– for new projects estimate and calculate the volume of bricks in a wall

Assume,

Length of brick wall (l) =10 foot

Height of brick wall( h) = 10 foot

Thickness of wall (b) = 1 foot

Now volume of brick wall = l × b × h

Volume of wall = 10 ×1×10 ft3

Volume of brick wall = 100 cu.ft

■**2) calculation of volume of brick**:- we have taken IS standard size of brick that is 190mm×100mm×100mm

Size of brick=190mm×100mm×100mm

Size of mortar thickness = 10 mm

Size of brick = 200mm×100mm×100mm

200mm = 0.656168 foot

100 mm = 0.328084 foot

Size brick =0.656×0.328×0.328 ft3

Volume of brick= =0.656×0.328×0.328 ft3

Volume of brick= 0.706 cu.ft

**■3) number of bricks**

= volume of wall/ volume of bricks

Number of bricks= 100/0.0706

Number of bricks= 1415 nos

**5) cement calculation in tile work of hundred square foot area**

**6) weight calculation of Steel bar and its formula**

**7) what is admixture of concrete and its types and its properties**

**4) wastage of bricks**:- we consider 5% wastage of bricks in storage and transportation and during the construction of building wall

5% bricks= (1415×5)/100= 38.5 nos

■** 5) opening in wall** :- brick wall if it has opening of door and window we should taken its size

Door size= 4 ft ×7 ft

Door volume = 4ft × 7 ft × 1 ft =28 ft3

Window size = 3 ft× 4 ft

Window volume = 3×4×1ft3 =12 ft3

**■ note:- wastage of bricks must be add in total calculation requirement of number of bricks and volume of opening like door and window must be deducted from total volume**
