CONCRETE RATIO TOOLS
Concrete ratio tools
Design a concrete mix, plan its volume, scale a cement batch and estimate material costs with connected calculators.
START WITH THE MIX
01Concrete mix design calculator
Choose M10–M60, see ingredient quantities and follow the scientific method.
Slab & footing volume
Calculate concrete volume from dimensions, then use it in your mix design.
50 kg cement-bag calculator
Scale a designed mix to the cement you have available.
Nominal mix calculator
Explore IS 456 Table 9 limits for M10, M15 and M20.
Concrete mix cost calculator
Price each ingredient using your own supplier rates.
Water-cement ratio calculator
Calculate water, binder or ratio and explore the strength reference graph.
Worked concrete mix examples
Three different lessons: minimum cement content in M20, strength-based selection in M25 and aggregate moisture in M30.
