Nominal mix concrete for M20
Nominal mix concrete is a type of concrete mix which is prepared by using approximate proportions of the ingredients without measuring them separately. The nominal mix is preferred for small construction works where the quantity of concrete required is not much.
M20 is a mix design of concrete which has a compressive strength of 20 N/mm² after 28 days of curing. The mix proportion for M20 concrete is 1:1.5:3 (cement:sand:aggregate).
Quantity of water required per 50 kg of cement
The water-cement ratio is an important factor in concrete mix design as it affects the workability, strength, and durability of concrete. The water-cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.
For M20 concrete, the water-cement ratio is 0.5. Therefore, the quantity of water required per 50 kg of cement can be calculated as follows:
Quantity of water = 0.5 x 50 kg = 25 liters
However, it is important to note that the quantity of water required may vary depending on the quality of materials and the environmental conditions.
Answer
The quantity of water required per 50 kg of cement for nominal mix concrete for M20 is 30 liters (option C).
