Description

This part of ISO 1920 specifies a method for determining the length changes of concrete specimens due to drying in air, and the method of preparing and curing the concrete specimens to be tested.
It is applicable for the testing of specimens prepared in the laboratory or in the field, in which the maximum
nominal size of aggregate in the concrete, in accordance with ISO 6274, does not exceed 25 mm.
The precision statement in Clause 10 does not apply to specimens that have had non-standard initial curing
(normally field-prepared specimens). In addition, this part of ISO 1920 requires that field-prepared specimens
be marked, recorded and reported as such.
NOTE 1 This test method is not always suitable for very low slump concrete (less than 20 mm), primarily due to the
difficulties in obtaining adequate compaction. Provided adequate compaction is obtained, the method is applicable.
NOTE 2 The method is specifically developed for measurement of drying shrinkage of concrete, but it is capable of
adaptation for measurement of length changes of specimens subjected to a variety of environmental conditions.
