Abstract

Reactive Powder Concrete (RPC) is composed of very fine powders (cement, sand, quartz powder and silica fume), steel fibres (optional) and superplasticizer. 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 GGBS as a replacement for cement at the percentage of 5% (RPC1), 10% (RPC2) and 15% (RPC3) by each is investigated. To compare the results of cement replaced mixture, specimen without cement replacement (RPC)are also casted. Performance of the various mixes is tested by the compressive strength, flexure strength and modulus of elasticity. The results show improvement in compressive strength, flexural strength and modulus of elasticity in cement replaced mixes.
