Methods of testing concrete, Method 13: Determination of the drying shrinkage of concrete for samples prepared in the field or in the laboratory
This Standard sets out a method for curing concrete shrinkage specimens in the laboratory, and for determining the length changes of these specimens due to drying in air. It provides for testing of specimens prepared in the laboratory or in the field in accordance with AS1012.8.4, in which the nominal size of aggregate in the concrete, in accordance with AS 2758.1, does not exceed 40mm.
