Cylindrical measures determine unit weight of concrete or aggregates and void content of aggregates. Precision-machined Cast Aluminum models meet ASTM C29 and 138 or AASHTO T19 and T121 requirements. Economical Welded Steel units can be user-calibrated for exact volume and used for non-specification testing. All Measures are watertight with top and bottom true and even, constructed to retain form under rough usage. Capacities range from 1/10 to 1 cubic foot (2.8 to 28.3L). Aluminum Strike-off Plates and Tamping Rods are ordered separately.
