As part of the materials selection process for underground repository sealings of nuclear wastes, all available Class H high sulfate-resistant HSR portland cements that were commercially available in the United States in 1981 were obtained for testing and evaluation. Four such cements were found. The Class H designation is that used by the American Petroleum Institute the HSR type is similar to a Type V portland cement as described in ASTM C 150 in that it is intended to impart high sulfate resistance to the cement by the absence or near absence of calculated tricalcium aluminate. Each cement was characterized by a combination of chemical-physical testing and X-ray diffraction examination it was concluded that all were generally similar and could be interchanged if such a need arose.
