Abstract: Mixtures of Ultra High Performance Concrete (UHPC) are generally composed of cement, micro silica, quartz powder, sand, short steel fibers, high range water reducing admixtures, and usually do not include coarse aggregates. Research work carried out at the National Building Research Center of the Technion, Israel, aimed to optimize the cost-effectiveness of these mixtures by incorporating coarse aggregated and improve the tensile properties of the composite with steel fibers, while maintaining reasonable workability of the fresh mixture. In the study, the compressive strength and workability of mixtures with various types of aggregates (quartz sand, flint, basalt, and dolomite limestone) were evaluated. In order to improve the tensile properties, mixtures with different fiber content were evaluated as well.
