The HEMSS 3T Experiment.

Abstract

As a result of this investigation, it was found that the HEMSS 3T cylinder successfully duplicated the conditions in the HEMSS No. 3 field-cast cylinder except for the slightly lower peak temperature. Generally, the measureable effects of high temperature on the grout properties were not significant. Large differences were found between measured and calculated strain values. Also, strains measured by two different strain gages were substantially different. These differences are attributed to differences in the coefficients of thermal expansion of the grout and the gages. Some fracturing or material degradation occurred near the periphery of the HEMSS 3T cylinders which was attributed to the thermal restraint effects of the corrugated steel culvert used as the forms. It is recommended that lubricated forms rather than corrugated culverts be used for the outer forms.
