These test sets are used to determine the time of efflux of a specified amount of fluid hydraulic cement grout, by allowing it to flow through a standardized flow cone. It can be used for with preplaced-aggregate (PA), but can also be used for other fluid grouts. The test method described in ASTM C939 determines the flowability by measuring the time of discharge of a 1.725L sample of grout as it is passed through a 0.5″ (12.7mm) orifice at the bottom of the cone.
Humboldt’s HC-2834S test set, which complies with ASTM C939, is comprised of a cast aluminum cone with a top ID of 7″ (178mm) and a replaceable orifice at the bottom of 0.5″ (12.7mm). The cone also includes an adjustable point gauge assembly, which is used to indicate the initial level of the grout sample. The set also includes a sturdy, tripod stand, which allows the cone to firmly fit into for testing (H-2833) and a 6L stainless steel beaker (H-2434SSB).
The test set is also available with a 0.75″ (19mm) orifice (HC-2835S), which does NOT comply with ASTM C939, but accommodates grout with larger aggregate.
All items of the set are available as individual items, please see replacement parts for these items.
