Effect of Carbonation on the Collapse Potential of Magnesium Oxide Treated Gypseous Soil

Collapsible soils are susceptible to large volumetric strains when they become saturated. Numerous soil types fall in the general category of collapsible soils, including gypseous which is characterized by relatively low density, appreciable strength and stiffness dry state, but significant deformations as a result wetting. The aim this study investigate effectiveness curing period time carbonation on magnesium oxide stabilization soil. In research, used improve using (0, 5, 10 15%) with two relative densities (35 75%) at different periods 1, 3 24 hours). Conventional collapse tests, single oedometer double odeometer modified test research effect improvement apparatus used. results illustrated that potential decreased more than 65% 55% for carbonated without treatment conventional tests test, respectively. A about treated 10% hours both test. accelerate well showed no clear change hours.
