The following is a design guide for selecting proportions for initial concrete mix design for normal weight concrete. This guide references ACI (Reapproved 2009), "Standard Practice for Selecting Proportions for Normal, Heavy weight, and Mass Concrete", specifically Chapter 6, "Procedure" and Appendix 1, "Metric (SI) System
In the United States, manufacturers rate different types or grades of concrete by strength, measured in pounds per square inch. Choosing the right grade of concrete means adequate support for your project, while the wrong grade can lead to cracks, flaking or failure.

What is Water Cement Ratio? Water Cement Ratio means the ratio between the weight of water to the weight of cement used in concrete mix. Normally water cement ratio falls under to as per IS Code 10262 (2009) for nominal mix (M10, M15 .. M25) We all know that water cement ratio will directly affect the strength of concrete.

The concrete mix ratio refers to the proportion of the components in the concrete. The concrete mix ratio is usually represented by the quality of various materials per cubic meter of concrete, or amount proportion of various materials. The basic requirements for the design of concrete mix ratio are: 1, meet the strength grade of concrete design.
Concrete Mix Design or Mix Design of Concrete is a procedure of determining the relative quantities and proportions of different ingredients of the concrete Cement, Water, Fine Aggregate, Coarse Aggregate, with the object of producing homogeneous fully compactable concrete having required Strength and Properties with economy.
