The durability of a reinforced concrete structure or structural element relates to its capacity to withstand its exposure environment, without the need for major repair over its service life. Realising concrete durability may be achieved using service life design. Service life design methods are used to ensure sufficient resistance of concrete structures to the exposure environmental actions. Avoidance of deterioration is a highly favourable option for the service life design of new structures. Surface treatment of reinforced concrete using hydrophobic impregnation (e.g. using silanes) may effectively be used for both corrosion control and avoidance of deterioration of reinforced concrete structures susceptible to chloride-induced corrosion. However, further studies are required to generate the statistical data and input variables required for the calibration and validation of service life prediction models for silane-treated structures.
