How Cement, Sand and Aggregate ratios influence

2021-2-25  Total Aggregate by cement ratio (A/C) decreases with increase in grade of concrete. For example, M20 grade of aggregate will have a higher A/C ratio than of M30; Higher the Aggregate/Cement ratio leaner the concrete mix, as cement content is lower. Concrete mix can be made more workable by fine tuning Aggregate/Cement ratio

Ratio of Steel required to Cement Concrete - Shyam

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
