18 x 3/8in Stainless Steel Tamping Rod
Tamping Rods are used in the consolidation of fresh specimens in test applications for the slump, air, and strength in accordance with many ASTM standards. The straight steel rods are round and corrosion-resistant, with tips at both ends. They come in varying sizes and are available in four models.
These rods are 24x5/8in (610x16mm) LxDia. This model has a measuring scale with 1/4in increments engraved on one side, while the the other has no measurement markings. Both models are for use in consolidating 6x12in (152x305mm) cylinder specimens. These meet ASTM C143 and AASHTO T 119 standards when testing the workability of fresh concrete with Slump Cones. They also conform to ASTM C31/31M for curing concrete in the field, and in testing air content by volumetric, gravimetric, or pressure method as indicated in ASTM C173, ASTM C138, T 152.
Tamping Rod is 12x3/8in (305x10mm) LxDia. It is required for testing in compliance with ASTM C31 as one of the methods of consolidation when molding 4x8in (102x203mm) cylinder specimens.
These rods is 18x3/8in (457x10mm) LxDia. It also meets ASTM C31/31M for consolidating 4x8in (102x203mm) concrete cylinder molds and complies with Canadian Standard CSA A23.2-3C.
Tamping rods also conform with other standards for preparing specimens and slump tests.
