Abstract: Chloride diffusion in concrete is commonly measured with an accelerated migration test (ASTM C1202) for ordinary concrete. However, the chloride diffusion within UHPC is very low and cannot be measured with precision. Thus, the results do not provide useful information for assessing the durability of structures made of UHPFRC. Thus, it is today crucial to develop a laboratory test which allows to discern the resistance of chloride diffusion for UHPFRC. This work investigates possible modifications to the standard migration test, as well as the effect of metallic and organic fibres on the chloride migration. The present results on chloride profiles of modified accelerated tests allow first interesting conclusion on UHPFRC durability against chloride.
