1.Introduction. The mass ratio of water-to-cement content is one of the most fundamental parameters in concrete mixture proportioning. The w/c ratio has a significant influence on most properties of hardened concrete in particular strength and durability due to its relationship with the amount of residual space i.e. capillary porosity, in the cement paste.
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 = wh20 / wc. = 8.33 qH20 / wc (1) where. r = water to cement ratio.
HOW TO CALCULATE WATER CEMENT RATIO. 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. If the mix lists the water in gallons ...
Water Cementitious Ratio calculator uses water_cementitious_ratio = Weight of Mixing Water / Weight of Cementitious Materials to calculate the Water Cementitious Ratio, The Water Cementitious Ratio formula is defined as the ratio of the weight of water mixed in the batch to the weight of cementitious materials in the batch.
Here, water cement ratio = 0.50 Water Cement ratio = weight of water / weight of cement Weight of water = 383.04*0.5 = 191.52 kg (ltr) From above method, we can calculate the quantity of sand, cement and water in mortar.

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 …. M25) We all know that water cement ratio will directly affect the strength of concrete.
Water is an important ingredient of a concrete mix and water cement ratio is an important factor in concrete or cement mix design. While working at site, concrete workers always try to add water in it so as to increase the workability of concrete but actually they are reducing the strength and durability of concrete.
How to Calculate Water Cement Ratio. For example, if the w/c ratio is 0.50 for concrete and cement is added is about 50 kg (weight of 1 bag of cement) Water required for concrete will be, Water/ cement = 0.50. Water = 0.50 x 50. Water = 25 liters = 6.60 gallon.
