Water-Cement Ratio Calculator
Concrete IS 10262:2019~1 min
Determine the water-cement ratio and water quantity for a given concrete mix.
Formula
Water = W/C ratio × Cement weight
Input Parameters
M20: 0.55 | M25: 0.50 | M30: 0.45
Results
Cement Weight
400kg
Water Required
180.0litres
Step-by-Step Method
- 1Determine the design W/C ratio from IS 10262 based on grade and exposure.
- 2Water = W/C ratio × Cement weight in kg.
Engineering Notes
- •Lower W/C ratio → higher strength but lower workability.
- •Maximum W/C ratio: M20 = 0.55, M25 = 0.50, M30 = 0.45 (IS 456 Table 5).
