Re view of the Rebound Hammer Method Estimating Concrete Compressive ...

Compressive strength of concrete can be determined by testing of moulded specimens or by core specimens drilled from existing structures. Moulded specimens, however, do not always represent the actual condition of structural concrete and drilling of core specimens from certain structural members is not always possible (because of risk of the loss.
