What is Reactive Powder Concrete (RPC)?

Reactive Powder Concrete(RPC) 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.
Reactive Powder Concrete was developed in France in the early 1990s and the world’s first Reactive Powder Concrete Structure, the Sherbrooke Bridge in Canada, was erected in july 1997. RPC is an ultra- high strength and high ductility cementitious composite with advanced mechanical and physical properties. It consists of a special concrete where the micro-structure is optimized by precise gradation of all particles in the mix to yield maximum density.
RPC is composite of very fine powders ( cement, sand, quartz and silica fume), steel fibers (optional) and superplasticizer. The superplasticizer, used at its optimal dosage, decreases the water to cement ratio (w/c) while improving the workability of the concrete. A very dense matrix is achieved by optimizing the granular packing of the dry fine powders. This compactness gives RPC ultra- high strength and durability. RPC have compressive strength ranging from 200 MPa to 800 Mpa.
