Ultra-high performance fibre reinforced concrete mix design in central Canada

Abstract

The mix design of ultra-high performance fibre reinforced concretes (UHPFRC) produced with locally available materials in Quebec and Ontario is presented. The procedure and results of the optimization of self-consolidating UHPFRC are discussed. The characterization of the retained mixes is presented with regards to strength, heat of hydration, shrinkage, chloride ion permeability, and freeze–thaw resistance. The results show that it is possible to produce self-consolidating UHPFRC with the targeted properties for use in precast products and in situ applications without requiring heat or pressure treatment during curing.
