Fine Aggregate Angularity Test Apparatus

 

This Apparatus is used to determine the uncompacted void content of a fine aggregate sample. The method indicates the angularity, sphericity, and workability of fine aggregate in a mixture for which it may be used. Each sample is mixed with a spatula until it is homogeneous. After filling the hopper, the sample is allowed to flow into the 100ml copper cylindrical measure. The measure has a locating hole to fit a lug on the Funnel Stand to ensure each sample is tested with precision and repeatability. Once the user strikes off excess material, mass is determined and void content is computed. 

Included with 100ml Cylindrical Measure, Funnel with specified hopper, Funnel Stand and a Glass Plate for calibration
