Sažetak
This paper presents a case study made on two high-rise buildings in Zagreb, the capital of Croatia. Two different non-destructive test (NDT) methods (pull-out testing with a Lok-test, and Schmidt hammer) were used for early age strength assessment. Parallel with NDT concrete strength tests cube testing was also done. An analysis of the results obtained show a correlation between pull-out strength measured by Lok-test and concrete cubes strength. The said correlation is compared with a previous laboratory correlation. According to the results obtained, a comparison of different NDT methods for early age strength assessment was made. It is recommended that a pull-out Lok-test should be used for early striking of formwork and thus for faster construction.
