Grades of concrete | Mix proportion | Water cement ratio | Slump value

Concrete is a mixture of different ingredients like cement, sand, aggregate, and water. When they are mixed with each other, it begins to harden with time. The strength of different grades of concrete depends upon the proportion of different ingredients used in the concrete. When cement is increased in the right amount its strength increases. …
