Fiber Reinforced Concrete Elements Exposed to Accelerated Corrosion
This study evaluates the structural performance of high performance fibre reinforced concrete elements affected by corrosion and its subsequent deteriorations.
With large scale applications already set in place and enhanced mechanical and durability performance, high and ultra-high performance concrete is the construction material of the present days. However, long term performance of structural elements exposed to harsh environments is still linked to the cracking pattern. Fibre reinforcement significantly improves the tensile strength of concrete, but serviceability cracks are nevertheless inherent. These cracks are the path through which the aggressive media travels to the embedded reinforcement, leading to the corrosion of the steel, the diminution of concrete cross-section, loss of reinforcement area, increased deformations and crack widths. Therefore, the present research is focused on the corrosion of the embedded traditional reinforcement and the loss of section in high performance fibre reinforced concrete elements with and without sacrificial zinc anodes. For this purpose, several small scale beam elements are exposed to artificial accelerated corrosion and their flexural behaviour assessed in comparison to non-exposed control elements.
