The experimental verification of concrete elements strengthened using ultra-high-performance concrete
Original language description
UHPC (ultrahigh-performance concrete) is a type concrete that has significantly better properties than commonly used concrete. In addition to the widely known high compression and tensile strengths, greater durability and resistance are also advantages of these types of concrete. These concretes can be used for both new structures and reconstructions. Nowadays, these types of concrete are in minority due to higher price and complex casting. This paper deals with the properties and behaviour of concrete structures strengthened using UHPC. One of the most important properties is a good bond between old concrete and the layer of UHPC. According to this fact, some types of bond were tested and evaluated. Then, using the most effective type of connection, experiments to determine and to compare values of bending load capacity both specimens strengthened using UHPC and without strengthening were made. Three types of elements were used; elements without strengthening and elements strengthened using 30 mm and 50 mm of UHPC. Besides the load bearing capacity, deformations and cracks were observed. Finally, measured values were compared with results of simplified calculations.
