### Water Cement Ratio of Concrete | Source of Undesirable

Generally, the water to cement ratio for the nominal mix ( M10, M15, M20, and M25) falls under 0.4 to 0.6 as per IS Code-10262 ( ). Lower water to cement ratio results in higher strength and durability but makes the concrete mix hard to work with and form. But this problem can be resolved by the use of plasticizers and superplasticizers.
