A Study on Properties of Reactive Powder Concrete

Abstract

The term reactive powder concrete (RPC) has been used to describe a fibre reinforced , superplasticized, silica fume-cement mixture with very low water-cement ratio, characterized by the presence of very fine aggregates instead of ordinary aggregate. It is having compressive strength about 150MPa. Fibres are incorporated in RPC in order to enhance the fracture properties of the composite material. Reactive powder concrete, is recognised as a revolutionary material that provides a combination of ultra-high strength and excellent durability. However, production of reactive powder concrete is not yet available with the limited research in this area. This paper investigates mechanical and fresh concrete properties of reactive powder concrete.
