The quality of the contact portland cement grout and surrounding rock will be of prime importance if grout is used to seal boreholes for the isolation of nuclear waste. The contact will need to be tight and relatively impermeable. In the study reported herein, simulated borehole SBH specimens were prepared and tested in the laboratory. The specimens consisted of grout poured into a hole in sections of anhydrite rock core that had been grouted into a steel pipe to provide restraint. The study was largely devoted to investigating methods of avoiding artifacts during preparation of these SBH specimens for study of the grout-to-rock contact. The work was conducted and is reported in two parts. The first part was a study in which only large round SBH specimens about 6 by 6 in. were used, while the second also included some smaller round SBH specimens about 3 by 3 in..
