Long-term performance of silanes applied on reinforced concrete bridges Christian Christodoulou Chris Goodier Simon Austin John Webb Gareth K. Glass 2134/34277 https://repository.lboro.ac.uk/articles/conference_contribution/Long-term_performance_of_silanes_applied_on_reinforced_concrete_bridges/9436565 Silanes can act as hydrophobic pore liners for reinforced concrete (RC) structures. They can significantly reduce the depth of chloride penetration, a major cause of steel reinforcement corrosion. However, there is little published information on their long-term performance. Thirty-two concrete cores were extracted from eight full-scale RC bridge supporting cross-beams that were treated with silane 20 years ago. Their water absorption by capillarity was measured and compared with sixteen control cores extracted from four non-silane treated RC cross-beams constructed at the same time. Results show that silanes may provide a residual protective effect against water even after 20 years of service. 2018-08-02 12:45:47 Silane Concrete Impregnation Built Environment and Design not elsewhere classified
