2021-12-6 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.

Type III or high-early-strength cement is a type of Portland cement that reacts quickly than conventional cement or Type I cement. The high-early-strength cement achieves around seventy percent of its 28-day strength in three days. The initial set of concrete made with Type III cement is within 45 minutes, and the final set is around 6 hours.

2006-5-6 For instance, a 4000 psi compressive strength concrete mix can have a widely varying modulus of rupture (anywhere from about 400 psi to 700 psi or so). The difference comes from the aggregate/paste interaction, so particle size and shape, along with paste integrity are keys to achieving good flexural resistance.
