ATTERBERG LIMIT LABORATORY PRACTICAL, Lab Reports of Geotechnical Engineering

The Atterberg limits are a basic measure of the nature of a fine grained soil. The Atterberg limits can be used to distinguish between silt and clay, and it can distinguish between different types of silts and clays.Atterberg Limit is divided into two small experiments, that is Penetration test or Casagrande test, and the second experiment is Plastic Limit test. For Casagrande test it is to get the liquid limit value.

PLASTIC LIMIT

TEST NO 1 2 3

Mass of container(g) 15.0 15.5 15. Wet Soil+container(g) 31.5 32.4 31. Dry soil+container(g) 30.0 31.0 30. Mass of dry soil(g) 15.0 15.5 15. Mass of wet soil(g) 16.5 16.9 16. Mass of water(g) 1.5 1.4 1. Water content (%) 10.0 9.0 10. PLASTIC LIMIT=9. CONCLUSION: From the experiment atterberg limit test, the limit optimum for liquid is 17.42 while for the plastic limit experiment, the recorded value is 9. CLEANELINESS AND NEATNESS:

  1. Explain ALL equipment that need to be cleaned and how to keep in place. Equipment that need to be cleaned are liquid limit device,spatula,grooving tool,glass plate and moisture can. Consult the manual or lab manager on any specific processes for cleaning demanding equipment and store equipment in a safe and clean container.
