Concrete / RCC Calculator
Cement, sand, aggregate and water for concrete — by mix ratio and element volume, with editable factors.
Wet concrete volume = 50 cft (1.416 m³). For a direct volume, set width and depth to 1.
Mix ratio (cement : sand : aggregate)

Dry-volume factor ≈1.54 for concrete. Water from the water–cement ratio (≈0.5). Cement: 50 kg/bag, 1440 kg/m³.
How it's calculated
Wet volume = 10 × 10 × 0.5 = 50 cft
Dry volume = 50 × 1.54 = 77 cft; total parts = 7
Cement = dry × 1/7 = 11 cft → 449 kg = 9 bags
Sand = 22 cft · Aggregate = 44 cft · Water = 0.5 × 449 kg = 224 L
