Abstract: The main goal of this research is to produce Ultra High Performance Fiber Reinforced Self Compacting Concrete (UHPFRSCC) in Gaza Strip, using materials that are available at the local markets. To meet this purpose, twelve trial mixes are used to obtain acceptable fresh and hardened properties of self-compacting concrete with a compressive strength exceeding 170 MP a. The fresh and hardened mechanical properties of UHPFRSCC like, workability, self-compacting properties, compressive strength, split cylinder strength and flexural strength are studied. The effects of using different amounts of steel fiber and silica fume contents on these properties are also investigated. Results show that it is possible to produce UHPFRSCC in Gaza Strip using materials that are available at the local markets if they are carefully selected and they will achieve a minimum compressive strength of 170 MP a at 28 days. This is expected to provide the local construction industry with a feasible new type of concrete which can be used for rehabilitation and strengthening purposes.
