The success of any geotechnical engineering design is heavily dependent on engineering properties of soils/rocks that involve with the project. Therefore, it is essential to measure engineering properties of soils/rocks accurately following the given standards and specifications.
- Give students some hands on experience on laboratory testing of geo materials
- Classify clay fines using plastic properties and identify its engineering applications
- Give experience on group work, data sharing, and reporting experimental findings
Students are required to work as groups. Each student in a group should:
- Read this sheet thoroughly prior to the practical session. The tutors will be available to oversee the sessions and answer questions
- Conduct the practical following the instructions given in this sheet.
- Clean up the equipment and area after the session
- Prepare a report, which consists of answers to all questions in “Calculations & Discussions” section of all three experiments. A formal report is not expected but data sheets (that you used to record the data during the practical and has the tutors’ signatures on) and answers to the given questions showing necessary calculations should be included in orderly manner.
a.Select a set of sieves and clean them
b.Measure the weight of each sieve and record
c.Stack the sieves in the shaking apparatus
d.Obtain about 500g of dry sand and pour it into the top sieve in the stack (Note: measure and note exact mass of sand before putting it into the top sieve)
e.Close the top sieve by using a lid and shake the stack of sieves for 3 ~ 5 min
f.Measure the mass of each sieve with retained sand and record the values
g.Remove the retained sand in each sieve and clean sieves
