The range is 0.35-0.45. WC ratio can take any value from the range.

For every kilogram of cement, about 0.42Kg of water is needed to fully complete hydration reactions.

However, a mix with a ratio of 0.42 may not mix thoroughly, and may not flow well enough to be placed. More water is therefore used than is technically necessary to react with cement. Water-cement ratios of 0.45 to 0.60 are more typically used. For higher-strength concrete, lower ratios are used, along with a plasticizer to increase flowability.
