Reactive Powder Concrete (RPC) is composed of very fine powders (cement, sand, quartz powder and silica fume), steel fibers (optional) and super plasticizer. A very dense matrix is achieved, and this compactness gives RPC ultra-high strength and durability properties. In the present study, performance of reactive powder concrete without quartz powder and containing Fly ash and Ground granulated blast furnace slag (GGBS) as a replacement for cement at the percentage of 5%, 10% and 15% by each is investigated. To compare the results of cement replaced mixture, specimen without cement replacement are also casted. Performance of the various mixes is tested by the compressive strength, flexural strength and split tensile strength. The results show improvement in compressive, flexural and split tensile strengths in cement replaced mixes.
