Abstract

In this paper, the sorption behavior of Ultra High-Performance Fiber Reinforced Concrete (UHPFRC) is experimentally investigated. As UHPFRC has a very low permeability, the sorption measurement presents an interesting challenge and has required the modification and optimization of the Dynamic Vapor Sorption Method (DVS) already applied for ordinary concrete. Indeed, the experimental results indicate that isotherm measurement on UHPFRC highly depends on the time step setup and the mass stabilization criteria in the DVS computer-controlled system. The results also showed that UHPFRC also has a strong sorption hysteresis (like other cementitious materials), but with a surprising triangular shape.
