AS 2350.13-1995 sets out the method for the determination of the drying shrinkage of portland and blended cement mortars of defined composition.

This Standard sets out the method for the determination of the drying shrinkage of portland and blended cement mortars of defined composition.NOTE: The test results indicate the potential performances of cement in mortar and concrete mixtures. It should be recognized, however, that drying shrinkage of mortar and concrete is affected by many factors other than cement.
