The present study aimed to determine whether certain correction factors used in the in-place prediction of compressive strength with concrete cores are directly applicable to self-consolidating concretes (SCCs). The parameters considered were core diameter, casting direction, core moisture, a number of variables intrinsic to cores, and concrete strength.Factors were also established for converting SCC 15 3 15-cm cubic specimen strength into 30 315-cm cylindrical specimen strength.The findings show that the correction factors recommended in EHE-08 and ACI 214.4R-10 overestimate the in-place compressive strength of the SCC analysed. The factors found for converting cubic into cylindrical specimen strength, in turn, were observed to differ from the values set out in the 2010 Model Code, but to be similar to the EHE-08 code proposals.
