The Fine Aggregate Angularity Apparatus determines the uncompacted void content of fine aggregates to determine angularity and sphericity properties that affect workability of mix designs. Gilson offers two models for this popular test. Each sample is mixed with a spatula until homogeneous and transferred to the hopper while the discharge opening is blocked with a finger. When ready, the sample is allowed to flow into the 100ml copper cylindrical measure. The bottom of the measure has a recess to fit a locating pin on the Funnel Stand to ensure precision and repeatability. The HMA-11A Spatula is purchased separately and meets specification requirements to strike off excess material. The specimen mass is determined, then void content is computed. Gilson recommends SC-74 Stainless Steel Pan to retain sample material.
SG-40 Includes a 100ml copper Cylindrical Measure, Funnel with specified hopper, Funnel Stand and a Glass Plate for calibration.
SG-40A features a strike-off guide for exact alignment of the spatula blade to the top of the Cylindrical Measure. This has been experimentally shown to improve repeatability of test results between operators as well as laboratories. A 100ml copper Cylindrical Measure, specified Funnel, Funnel Stand and a Glass Plate for calibration are included.
