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 1990’s by Bouygue’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.
