How to calculate concrete quantity for slab beam and column

---

How to calculate concrete quantity for slab beam and column. 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 quantity of concrete calculation 

1) quantity of concrete for slab
2)  quantity of concrete for beam
3) quantity of concrete for rectangular column
4) quantity of concrete for circular column

How to calculate concrete quantity for slab

*Given dimension of slab

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

4.62 m3 concrete quantity required for construction of slab

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

Calculate concrete quantity for Beam

* given measurement of beam

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

1.1088 m3 concrete quantity is required for construction of beam.

Calculate concrete quantity for rectangular column

* given measurement of rectangular column

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

1.6632 m3 concrete quantity is required for construction of rectangular column

Calculate concrete quantity for circular column

* given measurement of circular column

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

0.6528 m3 concrete quantity is required for construction of circular column
