Analysis of long-term influence of chloride aggressive environment on the UHPC

Ing. Radka Pernicová, Ph.D.

Depth of Chloride penetration of Ultra High Performance Concrete (UHPC) with dispersed reinforcement in long term horizon is determined in this paper. This work deals with the one dimensional chloride diffusion, which can be potentially dangerous particularly for the durability of concrete structures. For the simulation of aggressive environment there was used chloride solution, where the samples had been stored for one year. Measured data were examined in relation to the depth of penetration of chloride ions into the concrete structure. Comparative measurements with normal strength concrete have been done as well. The experimental results showed that UHCP have more improved resistance of chlorides penetration than NSC and also chloride diffusion depth is significantly lower in UHCP.
