Title: A study on Swelling Behaviour of Expansive Soils
Author: Mohammed, Mona Awad Siddig
Abstract: Investigation of swelling behavior is quite important in design of foundations on expansive soils. This research aims to study the swelling characteristic and behavior of expansive clays in Sudan. Intensive laboratory testing program was conducted on four soils collected from known areas of expansive soils in Sudan. The oedometer tests were carried out to measure both swell percent and swelling pressure for the compacted soil samples at their optimum moisture contents and maximum dry densities. The free swell index for disturbed soils was measured by stander graded cylinder. The results of the free swell index are range from 140 to 240 % for studied soils, where was the liquid limit and plasticity index values range from 74 to 92 % and from 45 to 75 %, respectively. The swelling pressure and swell percent values for the four soils are range from 192 to 325 KPa and 2.6 to 0.2 %, respectively. The study shows significant effects of soil index properties on the measured swelling parameters. It is clear that soils of high plasticity have higher potential for swelling compared to those of low plasticity. Conclusions are drawn from the study which is useful in design and construction of foundations on expansive clays
