Fine Aggregate Angularity Apparatus

Fine Aggregate Angularity Apparatus is used to determine the loose uncompacted void content of aggregate. This testing method provides an indication of aggregate spherical shape, angularity, and workability within a mixture. Test sample is mixed until homogeneous and poured into the funnel of the device while the funnel stem is blocked. The sample is then released into the 100mL Copper Cylindrical Measure. Excess aggregate is then struck from the top of the measure.

Any disturbance during this striking process that would cause compaction of the aggregate must be avoided for accurate test results. Model 9102-DJM includes a strike-off guide for more precise striking of excess sample. Once the material is leveled, the sample is weighed to determine the mass. Void content can then be calculated.

Features:

• Locating pin on the funnel stand reduces time between tests
• Strike-off guide (included with model 9102-DJM) increases repeatability
• Supports ASTM and AASHTO specifications
