The amount of water required depends on the air temperature outside, the humidity, the amount of direct sunlight, and the concrete mix ratio. The most important thing to remember about water is that the more there is in concrete mix proportions, the weaker the cement’s cured tensile strength, adhesive strength.
The water to cement ratio is calculated by dividing the water in one cubic yard of the mix ( in pounds) by the cement in the mix (in pounds). So if one cubic yard of the mix has 235 pounds of water and 470 pounds of cement- the mix is a .50 water to cement ratio.
Calculate water-cement ratio from the maximum free water/cement ratio according to environmental exposure condition as per table 5 of 456-2000, this is the limitation given by Indian Standard. Limitation chart for w-c ratio shows the maximum value of the w-c ratio as per IS 456: 2000 which can be adopted during mix design.
The water to cement ratio largely determines the strength and durability of the concrete when it is cured properly. The w/c ratio refers to the ratio of the weights of water and cement used in the concrete mix. A w/c ratio of 0.4 means that for every 100 lbs of cement used in the concrete, 40 lbs of water is added.
What is Water Cement Ratio? Water Cement Ratio means the ratio between the weight of water to the weight of cement used in concrete mix. Normally water cement ratio falls under 0.4 to 0.6 as per IS Code 10262 (2009) for nominal mix (M10, M15 ….

Water to cement ratio is the ratio of. weight of water to the weight of cement. used in a concrete mix and can be expressed as. r = w h20 / w c = 8.33 q H20 / w c (1) where . r = water to cement ratio. w h20 = weight of water (lbs) w c = weight of cement (lbs) q H20 = volume of water (US gallon) Example - Water to Cement Ratio
Water Cement Ratio: Water cement ratio can be defined as the ratio of the volume of water to the volume of cement used in a concrete mix. Water has a great role on the strength and workability of concrete.
Therefore, low water to cement ratio leads to serious problems in hardened concrete. When water to cement ratio is low in a fresh mix, then less water is available for the hydration of cement.Hence, some amount of cement paste remains un-hydrated that leads
