This document specifies the procedure for the determination of total shrinkage of concrete specimens in drying conditions. NOTE 1 Possible shrinkage or length changes occurring before 24 h of age@ and which may have significant amplitude and/or consequences@ e.g. for high performance concrete and/or in case of restraint@ may need to be measured according to a complementary procedure not covered by the present standard. NOTE 2 Information on a simplified procedure for the determination of autogenous shrinkage is given in Annex A. The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 32 mm.
