Evaluation the Compressive Strength in Concrete Structures Using the In-situ Test Methods

The new concrete Standards give rules for in-situ checking if the hardened concrete in structure achieved the designed compressive strength according the request the class of concrete. Different concrete elements in structure request the different access during the examinations and different analytical analysis. Using the different examination methods will be the main aim on evaluations of concrete strength, always in comparing with requested design class. Core testing and other nondestructive methods assessing strength of surface concrete are generally less reliable than cores, but less damaged will used for final evaluations
