Abstract:
Ultra‐high‐performance concrete is a class of cementious materials that is characterized by its high strength, ductility, and durability in comparison to conventional concrete. UHPC has a dense matrix and an ability to restrain crack widths, due to the inclusion of fibers, which has limited chloride ingress and resulting corrosion in many isolated accelerated testing environments. Further work is needed to evaluate the service life of these materials under combined mechanical loading and environmental conditioning, especially in long‐term testing environments. In this presentation, the results of long‐term chloride ponding experiments of reinforced UHPC beams are reported under uncracked and pre‐cracked conditions. Numerical simulations using three dimensional multi‐physics simulation techniques are also combined with the experiments to simulate deterioration processes and predict service‐life response.
