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. Gilson recommends SC-74 Stainless
Steel Pan as a sample retainer.

Included with the SG-40 is a 100ml copper Cylindrical
Measure, Funnel with specified hopper, Funnel
Stand and a Glass Plate for calibration. Est. Ship
