Influence of test specimen geometry on compressive strength of ultra high performance concrete
Existing recommendation for ultra high-performance concrete (UHPC) suggest cylinders with an aspect ratio of 2 (diameter/height) for determining compressive strength. The diameter of cylinder should not be less than 70 mm. Recommended dimension of cylinder are  7×14 cm,  10×20 cm and  15×30 cm. None of existing recommendations for UHPC had defined conversion factors for testing compressive strength on cylinders with different geometry. This is very important for practice because UHPC is tested on different samples and there is no correlation between results. In this paper experimental research is described in which compressive strength of different UHPC mixtures was tested on cylinders with different geometry. Furthermore, an analysis is done and conversion factors for testing compressive strength of UHPC on samples with different geometry are proposed.
