EVALUATION OF EXPERIMENTAL INSTALLATION OF SILANE TREATMENT ON BRIDGES. FINAL REPORT

In this project the effectiveness of silane-based chemicals as concrete sealants was evaluated for selected bridges throughout the state of Louisiana for a five-year period. The field evaluation was initiated after satisfactory results in the laboratory. In conjunction with this study, Louisiana State University conducted an additional investigation on detection of silane reaction using infrared spectroscopy. The results obtained from the field study indicated that the silane-based chemicals provide some hydrophobic characteristics. The effects are not long-lasting and absorption decreased to 30% improvement over the untreated surface after four years. No changes in the chloride content or the corrosion activities were observed in treated or untreated bridges. The results of infrared spectroscopy indicated a depth of silane penetration of between 0 and 0.1 inch in the treated bridges.
