Designing and Proportioning Normal Concrete Mixtures ...

The process of determining required and specifiable char-acteristics of a Concrete mixture is called mix can include: (1) fresh Concrete properties;(2) required mechanical properties of hardened concretesuch as strength and durability requirements; and (3) theinclusion, exclusion, or limits on specific ingredients. Mixdesign leads to the development of a Concrete Proportioning refers to the process of deter-mining the quantities of Concrete ingredients, using localmaterials, to achieve the specified characteristics of theconcrete.

stronger with time as long as there is moisture and a favor-able temperature available. Therefore, the strength at any particular age is both a function of the original water-cementitious material ratio and the degree to which the cementitious materials have hydrated. The importance of prompt and thorough curing is easily recognized.
