19、ctmthat can be expected when cracking occurs. A tensile strength of at least fctm 3 N/mm2shall be assumed for fct,eff. A lower value with fctm(t) may be used if the expansion of the crack ceases demonstrably within the first 28 days. If a lower value fctm(t) is used, this is to be indicated in the construction specification, the tender specification and on the design documents so as to give the person undertaking the work adequate notification to permit him to specify the concrete accordingly.
