Reactive Powder Concrete is a developing composite material that will allow the concrete industry to optimize material use, generate economic benefits and build structures that are strong, durable and sensitive to environment.RPC is an ultra high strength and high ductility cementitious composite with enhanced physical and mechanical properties. It was first developed in the early 1990â„¢s by Bouygueâ„¢s laboratory in France. It consists of a special concrete where its microstructure is optimized by precise gradation of all particles in the mix to yield maximum density. At the level of maximum compressive strength of concrete, the coarse aggregate becomes the weakest link in concrete. In order to increase the compressive strength of concrete even further, the only way is to remove the coarse aggregate. This philosophy has been employed in RPC. It is a material which can resist direct primary tensile stresses and having the potential to structurally compete with steel.
