Answer / ghizal

as the density of water is 1. if we multiply the water
cement ratio with the cement being used , we will get the
amount of water. For example if water cement ratio is 0.45
and cement being used is 400 kg per cum, then the water
required will be 0.45x 400=180 litres per cum of concrete.

Answer / bola oluyemi

indian-standard-code.html?cp=7
After reading that
click on M-15 mix designs, M-20 etc to get the ratios.

Remember there are ratios based on weight (mass) and volume.
So go through the tables and write down what you want and
explain to the others whether the ratios are by volume or
mass.

Answer / kapil gupta
