Strengthening of RC members by means of high performance concrete

Abstract

The possibility of using High Performance Fiber Reinforced Concrete for strengthening or repairing existing RC structures has been proposed in the last few years. The paper presents an overview of the different possible applications with this kind of technology. In particular, different materials, having different properties in terms of strength and workability, are available in order to optimize the application. In detail, self-leveling materials and thixotropic materials have been used. The use of jackets in High Performance Fiber Reinforced Concrete allows to increasing the bearing capacity, the stiffness and the durability of RC elements. A series of applications are presented and the obtained benefit are discussed
