Modifications of carbon fibre reinforced reactive powder concrete (CFRPC)

A new type of cement has been developed in Europe and Canada, called Reactive Powder Concrete {RPC), where w/c ratios of 0.1-0.14,fine particles were used. This particular formulation has achieved high compressive and flexural strength. Carbon fibres have been used widely recently due to its long-term durability. Dispersion of short carbon fibres was always a major problem when they were mixed with cement. The present research was mainly concentrated at carbon fibres dispersion in RPC by using various techniques: 1 ) mechanical-ultrasound; and 2) chemical-surfactants. Also, the influence caused by these dispersion techniques on mechanical properties of the RPC were studied. The results have shown that ultrasound has provided better improvements on dispersion fibres and also enhanced overall mechanical properties. Surfactants have contributed less significant effects on the mechanical properties due to possible loss in interfacial bonding caused by the surfactant molecules.
