Abstract
Reactive Powder Concrete (RPC) is composed of very finesteel fibres and superplasticizer. This Cohesive matrix gives ultra-high strength and durability properties. A comparison of the physical, mechanical and durability properties of RPC and high performance concrete (HPC) shows that RPC possesses better results compared to HPC. In order to increase the compressive strength of concrete even further than HPC, the only way is to remove coarse aggregate. This philosophy has been employed in what today known as Reactive powder concrete. The principal objective of this study is to prepare RPC120. In the present study, performance of reactive powder concrete without quartz powder and containing silicafume as a replacement for cement at the varying percentage of 0%, 5%, 10%, 15% and 20% by each is investigated. To compare the results of cement replaced mixture, specimens without cement replacement are also casted. Performance of the various mixes is tested by the Compressive strength, Flexure strength and Tensile strength. The results show improvement in compressive strength, flexural strength and Tensile strength in cement replaced mixes in Reactive powder concrete.
