Fine Aggregate Angularity Apparatus

    Fine Aggregate Angularity Apparatus


    The Fine Aggregate Angularity Apparatus determines the uncompacted void content of fine aggregates to determine angularity and sphericity properties that affect the workability of mixed 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. The SGA-93 Corrosion-Resistant Stainless Steel Pan retains sample material and meets applicable ASTM and AASHTO standards.

    SG-40 Includes a 100ml copper Cylindrical Measure, Funnel with specified hopper, Funnel Stand, and a Glass Plate for calibration.
