Answer / arulselvan

for columns 2-3%
for slabs 0.5-1.5%
for beams 1-1.5%
for piles 2-5%..

Example
Lets take example of RCC Column, where reinforcement required is 2 % of concrete volume, weight of steel required will be:
(2/100*1)*7850 (steel density )-per m3 steel-157 kg

Answer / rajesh kumar jha

Answer / utpal panchal

Required steel in concrete is Depend on Types on concreting different structure
For Example,
R.c.c Slab = 0.5 to 1 % steel Required in volume of concrete
R.c.c Beam = 1.8 to 2% % steel Required in volume of concrete
R.c.c column = 2.5 % % steel Required in volume of concrete
R.c.c Road = 0.6 % % steel Required in volume of concrete

(1) Here take Column 1 m3 concrete volume calculation is
(2.5 x 1/100) x 7850 =196.25 kg steel Required
(2) Here take Column 6.90 m3 concrete volume calculation is
( 2.5 x 6.90 /100) x 7850 =1354.12 kg steel Required
