Service Life Extension and CO₂ Emission due to Silane Treatment on Chloride-Exposed Concrete Structures

Abstract:

This study presents assessment of the environmental impact in terms of the CO₂ due to silane treatment for extending corrosion-free service life of concrete structures under chloride attack. To achieve this, there are two issues to be addressed; prediction of corrosion-free service life extension, and assessment of the amount of CO₂ emission. In predicting the corrosion-free service life extension, the behaviors of chloride diffusion before and after time-based silane treatment are considered. Then, the cumulative CO₂ due to silane treatment is accordingly calculated. The ratio of the corrosion-free service life extension to the cumulative CO₂ is defined as the effectiveness of silane treatment, and used to compare different silane treatment strategies.
