How do I obtain high early strength concrete? - ACPA

High early strength concrete (2500-3500 psi compressive in 24 hours) is usually accomplished using Type III high-early strength cement (see Table 1), high cement content (600-1000 lb/cu yd), and lower water-cement ratios (0.3 to 0.45 by weight). Super-plasticizers are also used to make the concrete mixture more workable during placement.

Advantages / Disadvantages

High-strength concrete must meet high-performance standards consistently in order for it to be effective. Second, careful materials selection is necessary. High quality materials must be used. These materials may cost more than materials of lower quality. Third, allowable stress design discourages the use of high-strength concrete.
