**How to calculate volume of concrete for slab beam and column.**

### * **introduction:**-in this topic we have to calculate volume of concrete for slab beam and column we know that concrete is made of mixture of cement sand and coarse aggregate and water so we should first calculate wet volume then we calculate dry volume.

### * **step of calculation:-**

### 1) volume of concrete for slab

2) volume of concrete for beam

3) volume of concrete for rectangular column

4) volume of concrete for circular column

### *1) **concrete volume calculation for slab**

### ***Given dimension:-**

### Length of slab = 6 m

breadth of slab =4 m

thickness of slab = 0.125 m

Volume of slab= l×b×t

Volume of slab = 6×4×0.125 =3m3

Wet volume of slab= 3m3

### (Note:-dry volume =wet volume×1.54)

### Dry volume = 1.54×3= 4.62 m3

**1)what is concrete and its types and properties**

**2) concrete quantity calculation for staircase and its formula**

**3) how to calculate weight of mild steel plate and derive its formula**

**4) calculate quantity of cement Sand for brickwork of 10m3**

**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**

### 2) **concrete volume for Beam**

### * **given measurement:-**

### Length of beam =6m

breadth of beam=0.3m

thickness of beam=0.6m

Volume of beam= l×b×t

Volume of Beam = 6×0.3×0.6=0.72 m3

Wet volume = 0.72 m3

Dry volume = 0.72×1.54 =1.1088 m3

### 3) **concrete volume of rectangular column**

### * **given measurement:**–

### Length of column =6m

breadth of column =0.6 m

thickness of column=0.3m

Volume of column =6×0.6×0.3=1.08 m3

Wet volume = 1.08 m3

Dry volume = 1.54×1.08

### = 1.6632 m3

### 4) **volume of circular column**

### * **given measurement:-**

### Height of column =6m

### Diameter of circular column=0.3m

### Radius

### = diameter/2=0.30/2=0.15m

radius of column=0.15m

Volume of column=πr2h

Volume of column

### =3.14×0.15×0.15×6=0.4239m3

Wet volume of column

### = 0.4239m3

Dry volume of column

### =0.4239×1.54=0.6528 m3
