本文件规定了在干燥条件下测定混凝土试样总收缩率的程序。 注1:24小时前可能发生的收缩或长度变化，以及在约束情况下可能产生的显著幅度和/或后果，可能需要根据本文件未涵盖的补充程序进行测量。 注2:附录a中给出了测定自收缩的简化程序信息。 该试验适用于混凝土中实际使用的骨料最粗部分（Dmax）的声明值不大于32 mm的试样。交叉引用:EN 12390-2EN 12504-1EN 12390-1EN 12350-1EN 1992-1-1:2004购买本文件时可获得的所有现行修订均包含在购买本文件中。

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 ofDof the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 32 mm.Cross References:EN 12390-2EN 12504-1EN 12390-1EN 12350-1EN 1992-1-1:2004All current amendments available at time of purchase are included with the purchase of this document.
