Abstract: In recent years, extensive research activities have been undertaken in the development of Ultra High Performance Concrete (UHPC). Concrete mixtures, material properties and design recommendations as well as structural behaviour of this new material have been studied over the last decades at different institutes. As a result, the essential properties of UHPC and design rules for the main stress states such as tension, compression, bending and shear are adequately understood.
Despite its extraordinary mechanical properties and excellent durability aspects, UHPC has mainly been used for pilot projects up to now. The main reasons for this are the lack of experiences for both engineers and builders, as well as the high cost of the raw materials and manufacturing technology.
The present paper deals with the development of a cost-effective UHPC Compound, which includes microsilica and quartz powder. The fine materials are homogenized in advance and are available as silo and bagged cargo. The standard cement from the silo in the plant is used additionally. The research results show that the production of HPC and UHPC is possible with the Compound and selected types of cement.
