The age at which concrete must develop its high strength is an important factor in the design of a mix. If high early strength is required, it can often be achieved by modifying an existing mix design to incorporate: (1) Type III rather than Type I or Type II portland cement; (2) additional cement; (3) an accelerator, such as calcium chloride; and/or (4) a water-reducing admixture.
