Concrete is made from locallyavailable materials and these materials determine the shrinkage potential. The design of concrete slabs, therefore, must be based on specific concrete mixtures. Specifying compressive strength and slump is not sufficient—mixes with the same strength and slump can shrink very differently in different regions.

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 specification.
