# Quantity of Water Required for M20 Grade Concrete

You will study the number of water that's required for M20 grade concrete.

The concrete is formed of cement, sand, aggregate and water. to accumulate the specified strength, it's extremely crucial to urge the water-cement ratio right. for each different quite concrete there's a special proportion.

Different quantity of water is required with the various grade of concrete mix. Shrinkage and creep can occur if excessive amount of water is employed .

M20 grade of concrete requires 200 liters or 53 gallons of water.

Given below may be a list of water required for various quite concretes:

The ‘M’ refers to the combination and value behind M refers to the Compressive strength of concrete in KN/cu.mat 28 days.

For M5 mix, whose ratio is 1:5:10, the load of cement (in kgs) is 141.00, the load of sand in Kgs is 785.00, water in liters required is 70.50

For M7.5 mix, whose ratio is 1:4:8, the load of cement is 174.00kg, the load of sand is 773kgs, water required for it's 87liters.

For M10 mix, whose ratio is 1:3:6, the load of cement is 226.00kg, the load of sand is 753.60kgs, water required for it's 113 liters.

For M15 mix, whose ratio is 1:2:4, the load of cement is 322kg, the load of sand is 717.80kgs, water required for it's 161 liters.

For M20 mix, whose ratio is 1:1.5:3, the load of cement is 403.20kg, the load of sand is 672 kgs, water required for it's 201.60 liters.

For M25 mix, whose ratio is 1:1:2, the load of cement is 565.00kgs, the load of sand is 565.00kgs, water required for it's 282.50liters.

For M30 mix, whose ratio is 1:1:3, the load of cement is 452 kgs, the load of sand is 452.00kgs, water required for it's 226 liters.
