The Void Content 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 filing the hopper, the sample
is allowed to flow into the 100ml cylindrical measure.
The measure has a locating hole to fit a lug on the
Funnel Stand to ensure each sample is tested with
precesion and repeatability. Once the user strikes off
excess material, mass in determined and void content
is computed. Pan as a sample retainer Included with
the 100ml copper Cylindrical Measure. Funnel with
specified hopper. Funnel Stand and a Glass Plate to
The strength of rock is an important property
which may measured in a number of ways.
Point-load strength testing is particulary useful
tes method which can be perfomed on specimens
requiring little oor no preparation prior to testing.
The test can perfomed on site or in the laboratory
with variations such as the diametral test, the block
test and the irregular lump test. Other application
include the determination on site of a strength index
for concrete and the prediction of cube strength
from point load index.
The tecnique enables the engineer to select
speciment of rock from eposed faces or bore holes,
observe orientation of fault lines, then set and
test the fault in the shear box.
