Nominal mix ratios for concrete are 1:2:4 for M15, 1:1.5:3 for M20 etc. Standard Mixes or Ratio The nominal mixes of fixed cement-aggregate ratio (by volume) vary widely in strength and may result in under or over-rich mixes. For this reason, the minimum compressive strength has been included in many specifications.

Reinforced Cement Concrete is the combination of concrete and steel bars (reinforcement bars). Concrete is a highly versatile construction material, known for its strength in compression. However, it has limited tensile strength and is prone to cracking under tension. To enhance its tensile resistance, steel reinforcement is incorporated.
