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.
