A State Of Art- On Development Of Reactive Powder Concrete

flexural tensile strength has number of undesirable consequences for its performance as an effective building material. These include necessity of auxiliary steel reinforcement and thick sectioned members that are both aesthetically unappealing and consume significant quantities of aggregates. An emerging technology with the potential to overcome these limitations is reactive powder concrete (RPC) RPC is a cold cast cementitious material in which the mechanical properties of the matrix are improved by suppression of the weak interfacial transition zone normally developed around the aggregate through improved particle packing and by refinement of the hydrated paste microstructure by extensive use pozzolanic silica and elevated temperature curing. Tensile capacity is provided by steel micro fibres rather than conventional reinforcement the low and non connected porosity of RPC also render extremely durable. RPC offers the possibility building with concrete with slender member with improved seismic response
