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.

This document describes the procedure for determining the creep (total, autogenous (basic) and drying) of hardened concrete test specimens subjected to a sustained longitudinal compressive load.

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.
