Empirical Time-Strength Relations of Concrete

Modern design concepts and intense competition with other structural materials make it necessary for the contractor of concrete structures to safely improve methods of scheduling concreting operations. Anticipation of the age at which concrete will be sufficiently strong for subsequent operations enables the contractor to plan equipment and personnel in advance of needs and to substantially reduce waiting time. Time-strength forecasting is of particular value in the scheduling of form stripping, removal of shores, handling or erecting precast structural elements, and transferring prestressing forces.
