How to Calculate Steel Quantity for Slab?

To get the approx. quantity of Reinforced Steel Bars we can use the following method.

Slab:

Minimum percentage of steel =0.7%

∴Quantity of steel = (0.7/100) x 1 = 0.007 m³
Weight of steel = 0.007 x 7850 = 54.95≊55 kg/m³

Maximum percentage of steel =1.0%

∴Quantity of steel = (1.0/100) x 1 = 0.01 m³

Weight of steel = 0.01 x 7850 = 78.5 kg /m³

Refer:- Quantity of Steel per m³

So, lets take an example

Here, Area of slab= 5.4 x 4.40 = 23.76 m^2

Assume thickness of slab = 120 mm = 0.12 m

∴ Volume of slab = 23.76 x 0.12 = 2.8512 m³

Let’s takes % age of steel as 1%

∴ QUANTITY OF STEEL REQUIRED FOR SLAB = 2.8512 m³ x 78.5 kg /m³ =223.82 Kg

Note:- To get the exact quantity of Reinforced steel bars you nee to “Design the slab (structural designing) based on the loads”
