# How To Calculate Staircase Concrete Quantity

Concrete amount calculation is that the commencement of the method of building a concrete steps. individuals got to knowledge a lot of of the required materials ought to they get therefore the construction would go basically. But, this is often a large operation, showing the scale of the steps and therefore the manner they’re gonna be build. solely this manner they'll calculate the requirement of the materials for the development.

**Staircase quantity****R.C.C. work (staircase)**

**Base Toe wall**

L X B X H 1.10 x 30 cm x 23 cm 1.10 x 0.30 x 0.23 = 0.076 cu. Meter

No. of Toe wall is one

Therefore, total volume of Toe wall = 0.076 x 1 = 0.076 cubic meter

Volume = L X B X H

Length of waist slab = L = 3.05 meter Breadth of waist slab = 1.15 meter

Adding bearing 15 cm 1.15 cm + 1.15 cm = 1.30 meter

Thickness of waist slab is 15 cm.

Therefore, volume of waist slab = L X B X H

Volume of waist slab = 3.05 x 1.30 x 0.15

Volume of waist slab = 0.594 m3

No. of waist slab is 2

Therefore, volume of waist slab = 0.594 x 2 = 1.190 m3

**Landings**

Length of landing = 2.30 meter

Add 15 cm bearing both ends

i.e. = 2.30 + 15 cm + 15 cm = 2.60 meter

Breadth of landing is 1.15 cm

Add 15 cm bearing as per drawing

i.e. = 1.15 cm + 15 cm = 1.30 meter

Thickness of landing slab is 15 cm i.e. 0.15 meter

Therefore, volume of landing = L X B X C

Volume of landing = 2.60 x 1.30 x 0.15

Volume of landing = 0.507 meter

No. of landing is 2

Therefore, total volume of landing = 0.507 x 2 = 1.014 cubic meter

**Steps without slanting**

Length of steps without slanting

= 2.3 m / 2 (As per drawing)

= 1.15 meter

Breadth of steps without slanting

= ½ x 0.25 (Triangle formula)

= 0.125 meter

Height of step without slanting is 16 cm

i.e. 0.16 meter

therefore, volume of step without slanting = L X B X H

volume of step without slanting = 1.15 x 0.125 x 0.16

volume of step without slanting = 0.023 m3 (cubic meter)

no. of steps is 20

therefore, total volume of steps without slanting = 0.023 x 20 =0.460 m3

steps with slanting’s

length of steps with slanting’s

= 2.3 m / 2 (As per drawing)

= 1.15 meter

Breadth of step with slantings

= ½ x 0.03 ( ie. 0.28 – 0.25 = 0.03) = 0.0153 meter

Height of step with slantings is 16 cm i.e 0.16 meter

Therefore, volume of step with slanting = L X B X H

Volume of step with slanting = 1.15 x 0.0153 x 0.16

Volume of step with slanting = 0.00281

No. of steps with slanting is 20

Therefore, total volume of steps with slanting = 0.00281 x 20 = 0.055 m3

Total volume of staircase is = 0.076 + 1.190 + 1.014 + 0.460 + 0.055

Total volume of staircase is = 2.765 m3 (cubic meter)
