Abstract : Expansion and subsequent shrinkage characteristics of shrinkage- compensating concrete were determined in mesh-reinforced prisms as well as in 'standard' Rubin bars. The maximum aggregate size was 3/8 inch. The specimens were cured in fog for 14 days and then subjected to drying in either 25% or 50% relative humidity (both at 73F). Although mixes were made with several different cement contents, most of the specimens were made with 7.5 sacks of cement per cubic yard. For comparison purposes, similar mixes were made with portland cement.
