Acceptance of Concrete Compressive Strength

The new concrete standards give directives regarding the checking if the hardened concrete conforms to the compressive strength requirements of the designed compressive strength class. The acceptance or rejection of conformity is the function of the compressive strength testing methods and the evaluation of the test results. In the paper through examples we show the role of the acceptance probability and the acceptance constant during the evaluation of test results and their significance during the conformity verification procedure.
