This practice covers field sampling and fabrication and initial curing of 50-mm (2-in.) cube specimens of non-shrink grout or mortar materials, or both. The values stated in either inch-pound or SI units shall be regarded separately as standard. The inch-pound units are shown in parentheses. The values stated might not be exact equivalents; therefore, each system must be used independently of the other. Note—“Unit weight” was the previous terminology used to describe the property determined by this practice, which is mass per unit volume. This standard was formerly designated as provisional standard TP 83.
