The evaluation of the structural capacity of existing structures and infrastructures requires the assessment of the actual in-place concrete strength. Direct and indirect methods to evaluate the concrete strength have been developed though the primary technique is the core test. In order to estimate the structural capacity of an existing structure the experimental data obtained by testing of cores were used to evaluate the specified in-place compressive strength according to the main standards such as EN 13791 and ACI 214.4R. The results obtained were critically evaluated, compared, and analyzed to assess the in-place concrete quality according also to the statistical methods proposed in ISO 12491. The procedures proposed by the standards studied give similar results though they are obtained following different approaches. |
