Influence of the specimen production and preparation on the compressive strength and the fatigue resistance of HPC and UHPC

Abstract The results of tests under monotonically increasing load and cyclic compression are often analysed by means probabilistic methods. Although there is a considerable scattering in the results, especially number cycles to failure, cause these cannot be completely explained. imperfections specimens tested among causes this mentioned literature. Based on round robin test influence HPC UHPC production specimen preparation techniques mean values compressive strengths, failure data have been evaluated. main findings study that an strength, however, do not affect failure. Moreover, accurate has positive strength both tests. influenced techniques, whereas polishing technique may specimens.
