    The time taken to achieve a specific strength is an important economic and design parameter in high strength concrete construction. In fact, a high early strength may bring far more practical and economic benefits than a high strength at a later age, in terms of early removal of formwork, increased productivity of precast units, early transfer of pre-stress, and early application of service loads.

  • How do I obtain high early strength concrete?

    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.

    Compressive strength of high strength concrete mix is usually greater than 6,000 pounds per square inch.. High strength concrete is made by lowering the water cement (W/C) ratio to 0.35 or lower. Often silica fume is added to prevent the formation of free calcium hydroxide crystals in the cement, which might reduce the strength at the cement aggregate bond.
