摘要：
The concrete based patrimony is subjected to different deterioration mechanisms, including steel corrosion induced by carbonation or chloride ion diffusion. Hydrophobic product may be used for protecting concrete structures against water ingress. No data are available on the correlation between quality of hydrophobic agent, concrete substrate properties and carbonation resistance. The influence of hydrophobic product and water to cement ratio of concrete substrate on the carbonation resistance has been investigated. The results show that there is a clear effect of hydrophobic treatment on carbonation resistance as well as chloride diffusion, specifically for high active product concentration and high W/C ratio.
