About this site

23 Testing of Volume Change Two tests that can be used to assess volume change in hardened concrete are the determination of the CTE (AASHTO TP 60-00) and the restrained drying shrinkage test ring (AASHTO PP 34-99). Neither test is adaptable to field applications, and thus they are of little value for moni- toring construction.
