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 calibration.
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.
