Table 6: Third group—estimate strength class by Pavicotti procedure. The comparison reported in Table 7 shows that the proposed formulation is able to estimate, with a good degree of approximation, the actual value of the potential strength of the concrete. In fact, the red letters indicate that the procedure has failed in the core strength estimation; with reference to the specimens appointed as MSC 1, the actual strength class is equal to C32/40. The estimated strength class via the application of the CSTR procedure is equal to C30/37 (indicated in red letters). The estimated strength class obtained via the application of the Pucinotti procedure coincides with the actual strength class (C32/40) and is indicated in black letters.
