What is concrete mix design?

Concrete mix design is defined as the appropriate selection and proportioning of constituents to produce a concrete with pre-defined characteristics in the fresh and hardened states. Moreover, concrete mixes are designed in order to achieve a defined workability, strength and durability . Finally, this article presents factors affecting the choice of concrete mix design.

Basis for selection and proportioning of materials 

The various factors affecting the choice of concrete mix design are:

1. Compressive strength of concrete
