Strengthening of Concrete Structures Using UHPC

Abstract:

UHPC (ultra-high performance concrete) is an excellent material applicable also for strengthening of existing structures. Recently published papers were focused mainly on the behaviour of strengthened slabs subjected to bending, in this paper, experiments on punching and on strengthening of columns are mentioned. Strengthening of bridge decks requires a special composition of UHPC with high fibre contents and with the ability of casting in the slope. The appropriate mix for UHPC was developed within the research project. The experience gained from the extensive experimental program resulted in development of rules for strengthening of existing structures using UHPC, which follow the European codes and Czech recommendations for design of structures made of UHPC.
