Early age history of concrete is crucial to determining how crete will be. Knowledge of the environmental effects on concrete at early ages is needed to predict concrete deflections and crack resistance. Properties of Concrete at Early Ages offers the information needed on properties of concrete at early ages for the engineer to ensure safe construction practices. Various topics presented include: field control and monitoring of concrete strength gain, the early-age behavior of reinforced concrete members, and mechanical properties in young concrete. Other topics are: early age shear strength, effect of early age construction loads on long term behavior of slab structures, and effect of accelerated curing.
