Improvement of Subgrade Clayey Soil using Eggshell
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 3
Abstract
Eggshell powder has not been used as a stabilizing material however, it could be a replacement for other types of stabilization. This study is aimed at determining the geotechnical properties of eggshell stabilized kuttanad clay with a view to determining its suitability as stabilizing agent for kuttanad clay. Laboratory tests were carried out on eggshell stabilized kuttanad clay and lime stabilized kuttanad clay. Lime stabilized kuttanad clay served as control experiment. The results of Atterberg limits, Hydrometer test, Free swell test, Unconfined compression test, Standard proctor test and California Bearing Ratio indicate that eggshell-stabilized kuttanad clay at 12% have similar engineering properties with Lime-stabilized kuttanad clay at 4%. Though from this study, eggshell powder mixed with kuttanad clay has been found to possess low binding properties, it can be used to significantly improve the strength of soil to be used as a sub grade where very high performance is not necessary. It could serve as a fair replacement for use as stabilizers for sub grade but not for base and sub base. The capacity as a stabilizer does not meet the minimum requirement for use as base and sub base materials for road construction.
