  • Ratio of Steel required to Cement Concrete

    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. Based on the construction type ratio of TMT Steel Bar to Concrete is: Civil Construction / Heavy Industrial Construction = 130 kg/m3
