Zimeena Rasheed,
Paragraph #1: Mention the lab performed, the date, and the location.
Casagrande experiment was performed in the lab to determine the liquid limit and plastic limit of
soil samples provided. Using the AASHTO classification table it is concluded that our soil
belonged to group A-4 (Silty soil). The liquid limit and plastic limit came to be 26.06% and
16.59% respectively. The plasticity index was 9.47.

Conclusion
Appendix
Based on the AASHTO classification our soil is categorized as silty soil with a Plasticity index
of 9.47, liquid limit 26.06, and plastic limit of 16.59%.

Introduction:
Water usually affects the properties as well as the state of soil as described by Atterberg limits(
Plastic and liquid limit). Silty soil has an earthy like smell with about grain size between 2mm to
0.05 mm. The sample behaves just like plastic and is deformable at the plastic limit while at the
liquid limit it flows just like liquid water.

Apparatus:
Grooving tools, electronic balance, Casagrande apparatus, oven, mortar, etc

Soil Boring Lab 2

The steps performed during the lab are as under:
• Add the gradually water into the sample till the soil becomes like a thick paste.
• By using the spatula place a portion of soil sample paste in a cup.
• Cut a straight groove through the sample.
• Try to make two blows per second in the device and note the number of blows at which
both the surfaces come back in contact with each other.
• Keep on performing the test from drier to a wetter condition in the lab by addition...
