Experiences with Ready Mixed UHPC for Strengthening of Concrete Structures

Popis výsledku v původním jazyce

This paper focuses on experience from strengthening works, done with ready mixed UHPC delivered on building sites by truck mixers. The first part is a summary of the results from the research project. This research project was focused on the quality of the existing concrete surface and the connection between the old concrete structure and the new strengthening layer made of UHPC. The main part of the paper focuses on two projects in which UHPC was used for strengthening and where the results from the research project were used. For UHPC quality control on the second project the new guidelines TP ČBS 07 were used. These guidelines, made and published by the Czech Concrete Society, have been valid in the Czech Republic since 2022. The first project is a small bridge reconstruction in Meziboří, where UHPC was used for strengthening of the bridge abutments. The ready mixed UHPC was transported from a concrete plant over a distance of nearly 110 km (68 mi), but especially for small project like this (11 m3 (14 cu yd)) it is a very effective solution. The second project is the strengthening of the bridge deck of Barrandov bridge in Prague. For this project about 400 m3 (523 cu yd) of ready mixed UHPC was used, transported by truck mixers from a concrete plant over a distance of nearly 14 km (8 mi).
