Interpretation of in-situ concrete strength test results
A full scale insitu reinforced concrete building frame built in a laboratory provided an opportunity to assess the use of the in-situ pull-out test on a systematic basis during construction. Interpretation of strength correlations should take into account the uncertainties that exist and therefore should be made by the use of standard statistical procedures. Two procedures recently adopted by BS EN 13791:2007 'Assessment of in-situ compressive strength in structures and precast concrete components' for estimating the in-situ characteristic strength of a test region from in-situ test results have been examined. Both procedures account for the uncertainty of the strength correlation by requiring either the lower 95 % confidence limit curve or a curve shifted downwards by a margin to be used. Overly conservative estimates of the in-situ characteristic strength are found to result.
