Concrete Calculator

Calculate cement bags, sand, and aggregate (gravel) quantities for concrete work. Supports multiple concrete grades: - M10 (1:3:6) — Lean concrete, PCC, leveling - M15 (1:2:4) — Non structural elements like PCC - M20 (1:1.5:3) — Standard RCC slabs, beams, columns - M25 (1:1:2) — Higher strength RCC structures Structure types: Slab, Beam, Column, Footing, Foundation, Custom. Uses dry volume conversion factor of 1.57. Results include cement bags (50 kg), sand volume/weight, aggregate volume/weight, and approximate water requirement. Input in meters or feet, output in SI or FPS units. Supports multiple units (quantity) and wastage percentage.
