Scope

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 could have significant amplitude and/or consequences, in case of restraint, could need to be measured according to a complementary procedure not covered by this document.

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.

Purpose

Result from SR to revise to homogenise maximum instrumental measurement uncertainty for scales.
