This standard describes the reference method used for type testing and in cases of dispute, for determining the effect of aggregates on the drying shrinkage of concrete. For other purposes, in particular factory production control, other methods may be used provided an appropriate working relationship with the reference method has been established.This standard is based on the testing of concretes of fixed mix proportions and aggregates of 20 mm maximum size.NOTE 1 Guidance on the use of larger size is given in Annex A. Precision data is not available for variations in size and for variations in the water content of the test concrete.NOTE 2 In those cases w
