Abstract
A new class of concrete that exhibits greatly improved strength and durability properties has recently been developed. Ultra High Performance Concrete (UHPC) is a steel fibre reinforced concrete consisting of optimal gradation of fine powders and a very low amount of water cement ratio. This paper describes the possibility of utilizing marble dust in UHPC based on various literatures. UHPC can be manufactured by eliminating the pores to create dense mix. Marble dust has very low fineness value so that it can be effectively utilized in UHPC. The Properties of marble dust indicate it can be a best alternative material in UHPC. Due to low fineness and high hardness value it could be possible to achieve a new class of UHPC with high strength and low permeability. This concrete has very wide areas of application such as bridges, storage structures etc. It has very high ductility value so that it can be used in earth quake prone areas.
