Important Tips
- Waste: Add 5-10% extra for waste and spillage
- Mixing: Don't mix more than can be poured in 45 minutes
- Water: Water-cement ratio shouldn't exceed 0.5
- Curing: Keep concrete moist for at least 7 days
- Quality: Use high-quality materials for structural work
About This Tool
The Concrete Calculator helps you estimate the amount of concrete and materials needed for various construction projects. The calculator supports multiple shapes and calculates cement, sand, and gravel quantities based on selected mix ratios.
Mix Ratios:
- M15 (1:2:4): For ordinary non-structural work
- M20 (1:1.5:3): For standard structural work
- M25 (1:1:2): For heavy-duty structural work
