When there is too much water in your concrete mix, however, it will have the opposite effect and the mix will be 'swamped', which will lower the rate that the chemical bonds form and therefore reduce the strength of the cured concrete. via
Does wetting concrete make it stronger?
ANSWER: Keeping concrete moist helps the curing process. If too much water is lost from the concrete through evaporation, the hardening process slows down or ceases. Concrete continues to gain strength after pouring for as long as it retains moisture, but the longer it moist-cures, the slower the rate of strength gain. via
