Reactive powder
concrete (RPC) is the term has been used to describe a fibre reinforced , super
plasticized, silica fume- cement mixture with reduced water-cement ratio,
characterized by the presence of very fine quartz sand instead of ordinary
aggregate. In this investigation the mechanical property performance of RPC has been investigated by varying
the water dosage, silica fume dosage, and with addition of 1%, 2%, 3%, 4%and
5% crimped steel fibres.RPC have also been investigated under different
combinations of normal water curing, hot water curing and high temperature
curing, after this 7 days of curing regimes, the specimens were cured in water
until the testing. Test results indicate that compressive strength of RPC
increases significantly after heat treating compared to the standard water
curing. Temperature, Rate of heating and Rate of curing also influenced the
mechanical performance of RPC considerably.
