The liquid limit is the water content corresponding to 25 blows, and it is usually expressed as a number and not a percentage. Report to the nearest whole number. Plastic Limit: 1. Calculate the water content of the three samples taken. 2. Average these three values, which gives you the value of the plastic limit. Report to the nearest whole number.

Engineering Reporting: 1. Complete the data sheets and record the liquid limit, the plastic limit and calculate the plasticity index to the nearest whole number. 2. Use the plasticity chart (for the Unified Soil Classification Chart) to classify the type of soil tested. 3. From the data in the following table, calculate the “Activity of the Clay” and determine the “Mineral Type”. *These values ARE NOT from the soil you tested in the lab, this is in addition to what you tested. Data from an unknown source Plasticity Index 21 %D<2µm 55% *utilize the graph provided in the lecture notes Questions: The following is a list of questions (to be...
