How To Calculate Water Content For 1 m³ M25 Concrete?
The calculation of water content for 1 m³ M25 concrete is very easy and simple.
We just need to know:
1. Consumption of cement per m³
2. Water-cement ratio.
Here, Grade of concrete is M25.
If it’s a design mix, both of these parameters shall be obtained the laboratory.
In absence of this information, let’s proceed by some assumptions:
Cement required for 1 m³ of M25 grade concrete is 9.51 bags.( Standard data)
As we know 1 bag of cement contains 50 kg of cement.
∴ 9.51*50 = 476 Kg of cement.
Let’s assume that the water cement ratio is 0.5.
Remember the formula :
W/c ratio =Water content /Cement content
Water content= Cement content x W/c ratio
Water content = 476 Kg x 0.5 = 238 Kg.
We know, 1 Kg =1 litre
So water content= 238 Kg. = 238 Litres
Add 5% wastage of water during mixing, handling,
∴ Water content = 5×238/100 + 238 = 250 litres.
