Recommended standards for small-scale ice strength tests
Butkovich, Theodore R.
Technical ReportSummary: The effects of specimen size and shape on the strength values obtained with small-scale unconfined compressive tests are shown. Results are given that show that a loading rate of 0.5 kg/cm^2-sec is required for all small-scale strength tests to minimize plastic effects which accompany slow loading of ice. The ring test, which is a useful new type of test to measure the tensile strength of ice, is described. Recommended standards for specimen size, shape, and configuration, along with loading rates and equipment are discussed.
