Abstract: 
In the EN 13670 “Execution of Concrete Structures” guidelines are given for the curing. In Switzerland these guidelines were slightly modified and introduced into the standard SIA 262 “Concrete Constructions”. The concept of the requirements for curing is based in one table on the strength development related to the specified strength. In a second table, the length of the curing period is given in number of days. The number of days depends on the reactivity of the concrete (r-value), the curing class and the temperature of the concrete surface. In a research project, funded by the Swiss Road Authorities, ASTRA, it was investigated if the different approaches (strength development and fixed number of days) lead to similar concrete properties and if these regulations are valid for durability properties like the resistance against carbonation, chloride and freeze-thaw and de-icing salt resistance as well.
