Abstract :
[en] 1. Inventory of concrete cultural patrimony in Wallonia 2. Collection of information about existing techniques used for in situ and laboratory investigations is needed before designing operating requirements. A description is provided and testing procedures are applied for evaluating quality of concrete of Saint- Vincent church. 3. Effect of hydrophobic treatment on corrosion delay. Hydrophobic products are used for protecting concrete structures against water ingress. They may also have a delay effect on steel corrosion by diminishing carbonation speed and H2O availability. This effect will be studied in laboratory but also on site: special concrete samples will be provided on the base of mixes (type of cement, W/C, …) observed on site and submitted to accelerated ageing into CO2 incubators. Result of investigations will support modeling of CO2 ingress.
