Nominal Mixes can be adopted only upto the grade of M20, but above m20 grade, a concrete must be mix designed as per code provisions. Though most of us uses Nominal mix of 1:1:2 for M25 Grade, but it shouldn't be done. There are various methods of concrete mix design, some of them are as follows : • Indian Standard I.S: 10262-2009 method.

The basic requirements for the design of concrete mix ratio are: 1, meet the strength grade of concrete design. 2, meet the concrete peaceability. 3, meet the durability of the use of concrete. 4, meet the above conditions to save cement and reduce the cost of concrete. The strength of concrete is divided into twelve grades, such as C7.5, C10

GRADE OF CONCRETE. Concrete of Grade is a mixture of Portland cement, water, and coarse and fine aggregates. It consolidates into a hard mas because of a chemical reaction called hydration between cement and water. Proportioning a concrete mix for a given purpose is thus the art of obtaining a suitable ratio of the various ingredients of concrete with the required properties at the lowest cost.
