Approximate Water Requirement (Amount) For Cement Bag & Various Concrete Grades (Mix Ratios)
Concrete is a mixture of cement, aggregates and water. Concrete aggregates include the fine and coarse aggregates.
Normally a concrete mix design stipulates the various percentages of these important concrete elements.
In this post, you’ll find an approximate Water requirement in litres for various concrete grades per cement bag.
A bag of cement usually contains 50kg by weight of cement.
Below is concrete mix ratio and water requirements for 50kg of cement.
1:3:6 = 34 litres of water
1:2:4 = 30 litres of water
1:1.5:3 = 27 litres of water
1:1:2 = 25 litres of water
Above figures could get you started right away in executing your water cement ratio on site without wasting much time on calculations.
