Answer Posted / pinku gautam
A water/cement ratio of only 0.38 is required for complete
hydration of cement. (Although this is the theoretical limit, water cement ratio lower than
0.38 will also increase the strength, since all the cement that is added, does not hydrate)
Water added for workability over and above this water/cement ratio of 0.38, evaporates
leaving cavities in the concrete. These cavities are in the form of thin capillaries. They
reduce the strength and durability of concrete. Hence, it is very important to control the
water/cement ratio on site. Every extra lit of water will approx. reduce the strength of
concrete by 2 to 3 N/mm2 and increase the workability by 25 mm
