This free course, Volume Change Behaviour of Unsaturated soils, begins by explaining how the volume of unsaturated soils can change and how the free swell test is conducted. You will then be introduced to the swelling behaviour of soils and how the swelling pressure of soil can be estimated. You will also learn how the volume change behaviour of soils can be obtained from suction controlled tests.
Next, the course goes further on to discuss the swelling and collapsible behaviour of Loess and Kaolin soils. You will also learn about the differences between the Bentonites and Kaolin soils. The course also presents some laboratory tests demonstrating how the volume Kaolin and Bentonites changes in the presence of water and kerosene. Lastly, you will be introduced to the sensors and devices used in measuring the moisture content of soils.
It is important, as an engineer or soil mechanics expert, to understand which types of soil are safe on which to plan and construct buildings. If you want a better understanding of the sort of soils that are safe to build structures/buildings on, you should take this course.
