Our Cement Concrete Calculator calculates cement bags, sand, and aggregate for any concrete mix ratio (M5 to M25). Supports 8 shapes — Slab, Beam, Column, Footing, Staircase, Circular, Trapezoidal, and Road. Includes donut chart, cost estimation, and step-by-step formulas.
M5=1:5:10 | M7.5=1:4:8 | M10=1:3:6 | M15=1:2:4 | M20=1:1.5:3 | M25=1:1:2
Dry volume = Wet volume × 1.54 (accounts for 54% bulking).
Approximately 8 bags (50 kg each) per cubic meter of M20 concrete.
