Applications of innovative concretes (SCC, HPC, RPC) in the building, civil and environmental engineering

During the last decades, new cementitious materials were available. These represent a sort of technical revolution with respect to the traditional concretes. The most important innovative High Tech materials are: Self-Compacting Concrete (SCC), High Performance Concrete (HPC), and Reactive Powder Concrete (RPC). In the present paper the compositions, the performances and some practical applications are shown. In particular, some performance improvements carried out in our laboratories are evidenced for these specific uses: a) SCC for a Building Engineering application (S. Peter Apostle Church in Pescara, Italy) with white concrete characterized by a marble-like skin; b) HPC in form of concrete with compressive strength over 90 MPa devoted to a work in the field of Civil Engineering (World Trade Center in San Marino); c) RPC in form of a fiber-reinforced concrete with a high fracture energy (40 kJ/m2) devoted to a special work in the area of Environmental Engineering (dumping of radioactive nuclear wastes).
