Comprehensive Characterization of UHPFRC Mixes for Seismic and Durability Rehabilitation of Bridge Piers

Sevigny-Vallières, C. / Marchand, P. / Terrade, B. / Roy, N. / Toutlemonde, F. / Tagnit-Hamou, A.

Towards design of UHPFRC jacketing for rehabilitation of bridge piers, one UHPFRC mix has been extensively characterized in order to provide the necessary material characteristics for such a design verification process. This mix is an innovative environmental-friendly UHPFRC mix, comprising recycled glass powder as cement and quartz powder replacement. The mechanical characterization of the mix comprises compressive strength and its evolution, Young’s modulus at early age and mature state, development of autogenous and total shrinkage, and tensile behaviour identified by flexural testing both on standard prismatic specimens as well as on thin plates representative of the UHPFRC jacketing layer cast around the existing concrete pier. Development of this effort has been undertaken in a joint project within ECOMAT international laboratory with Université de Sherbrooke (Canada) and the Materials and Structures Department of Université Gustave Eiffel (France).
