My final year students taking up Geotechnical Engineering were trying their hands on compacting soil sample. The value obtained from this compaction test serves as a guideline to determine the compactive effort on-site. I instructed my students to perform 5 sets of this test. The mould was filled with three layers of soil, and 27 blows for each layer.
Can't blame them for looking so gloomy in these pics. :P It was quite tiring, I must say..kekeke..the rammer is 2.5 kg.
