Grade of Concrete | Concrete Grade Ratio | M10,M15,M20,M25

In this video you will learn about grades of concrete and it’s ratio.

“Mixture proportioning refers to the process of determining the quantities of concrete ingredients to achieve the specified characteristics of concrete.”

“The process of relative proportions of cement, sand, coarse aggregate and water, so as to obtain a concrete of desired quality also known as proportioning of concrete.”

The first table shows grade of concrete, mix proportion (cement, sand, aggregate), and the ratio.

The second table details designation, mix proportion, characteristic compressive strength, and group.
