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
