Reactive Powder Concrete (RPC) is characterized by high cementitious material content, very low water to cement ratio and steel micro-fiber reinforcement. This type of cementitious composite has greater ductility, durability and mechanical properties compared to traditional concrete. Abrasion resistance of the composite material is still not well understood,although it has a variety of applications, including bridge deck construction and floor covering. In the scope of this study, three water-to-cement ratios and various micro-fiber volume fractions were investigated. Mechanical properties under steam curing were determined. Cubic specimens with a 71 mm side were prepared for the surface abrasion test by means of Böhme apparatus. In addition, the flexural toughness and Charpy impact tests were performed on unnotched prismatic specimens. A relationship between loss of mass by the Böhme abrasion test and mechanical properties was investigated. Test results indicated that abrasion resistance and mechanical properties can be improved by incorporating steel micro-fiber. The positive effect of fibers can be enhanced by reducing W/C ratio. It seems that RPC has a great potential to use in civil engineering structures subjected to abrasion.
