24 x 5/8in Stainless Steel Tamping Rod
Tamping Rods are used in the consolidation of fresh concrete specimens in test applications for the slump, air content, and strength in accordance with many ASTM and AASHTO standards. Stainless steel rods are corrosion-resistant, with ends rounded to a hemispherical tip at both ends. They come in various lengths and diameters and are available in four models.
Tamping Rods are round in cross-section and measure 24x5/8in (610x16mm) LxDia. The HM-48 model has a measuring scale with 1/4in increments engraved on one side, while the HM-48A model has no measurement markings. Both models are for use in consolidating 6x12in (152x305mm) concrete cylinder specimens. These rods 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 specimens in the field, and in testing air content in concrete. They also meet ASTM C173 and AAST standards for testing the air content in the air. For testing in-place concrete strength, products like the Concrete Test Hammer, ASTM C805 can be used.
Tamping Rods are round in cross-section and 15. HM-47 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) concrete cylinder specimens.
HM-63 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. When used with Humboldt HCM-2500 Series compression machines, a Humboldt Load Frame, Concrete Cylinder Loading Shelf is essential for accurate testing results.
Tamping rods also meet other standards for preparing specimens and slump tests. These include AASHTO M 205 and British Standard BS 1881.
