TMT Bars required in RCC for Foundation, Beam, Slabs | Shyam Steel

Ratio of Steel required to Cement Concrete In civil engineering the thumb rule for Steel to Concrete ratio is 100:130. The ratio means for every 130 kg concrete 100 kg of steel is needed. 100 kg of steel strengthen the structure in RCC. Failing this ratio of steel to concrete would cause weakening the structure and fatal cracks to it.
