### How to calculate the water-cement ratio for concrete

First of all, what is Water Cement Ratio??. Waterc ement ratio is the ratio of weight of water to the weight of cement. It's normal value lies between 0.4 to 0.6 as per IS code 10262 (2009) for nominal mixes.. Concrete is a macro content and contains cement, sand, coarse aggregate, fine aggregate and water.
