Concrete mix design is often mistakenly referred to as "cement mix design." However, cement is simply one of the ingredients of concrete. It is a binding substance that allows concrete to set, harden, and adhere to other materials. Therefore, it cannot and should not be used interchangeably with concrete mix design.


Different concrete mix designs with different materials, even with the same proportions, can have significantly different properties of strength and durability. The properties of concrete can also be affected through production, placement, finishing, and curing practices. It is therefore important that concrete mixes are designed,


acteristics of a concrete mixture is called mix design. Characteristics can include: (1) fresh concrete properties; (2) required mechanical properties of hardened concrete such as strength and durability requirements; and (3) the inclusion, exclusion, or limits on specific ingredients. Mix design leads to the development of a concrete ...
