A State of the Art Report on Ultra High Performance Concrete: Reactive Powder Concrete

Abstract

Abstract:-There has been continuous demand for materials with higher compressive strength for various civil engineering applications. Reactive powder concrete (RPC) has been developed to overcome the weakness of most high strength concrete available with compressive strength in the range of 60-100 MPa. RPC was developed from a special combination of constituent materials such as Portland cement, silica fume, quartz flour, fine silica sand, high-range water-reducer, water and steel fibers wherein attempts have been made to remove the coarse aggregate particles to make a very strong mortar with a very low water cement ratio. This paper presents a state of the art report reviewing the research in the area of the development of RPC, highlighting the enhanced performance in the mechanical properties of RPC in direct application of its use in structural members requiring high standards of strength coupled with superior performance and durability.
