bentonite." The most important bentonite clay resources are located in the Afar region, as they are easily accessible from the main road connecting the capital city Addis Ababa to neighbouring Djibouti. Junior Research Geologist, Chala Dida, has been charged with obtaining more samples of bentonite for further testing by the Ministry.
Based on the test result and discussion, the following conclusions can be drawn: (1) Compacted sand–bentonite mixture swells or collapses upon wetting, dependent on its density, water content, mixing ratio and the stress state. (2) The swelling of bentonite is mainly due to the water absorption of montmorillonite.
