ABSTRACT
Clayey soils with high content of clay particles cannot be used for either construction due to their weakness. In order to overcome the identified weakness several techniques have been tried to make the soil suitable for construction. The study used combination of cement and egg shell powder to analyze the properties of clayey soil. Components of Eggshell are magnesium, carbonate, protein and calcium. This research work was carries out in investigate the properties of an Omu- Aran lateritic clay soil stabilized with eggshell powder. A varying percentage of 0, 2, 4, 6 and 8% of eggshell powder, cement and eggshell powder (ratio 1:1) and cement were added to the lateritic clay soil in order to stabilize it. Various laboratory tests which include the basic geotechnical test (such as particle size distribution, density specific gravity, natural moisture content and Atterberg limit) and strength test (i.e. CBR and U C S) were carried out on the sample. The results of the laboratory test showed that there was a significant improvement in the properties of the stabilized specimen. The results also showed that for this study, when cement is mixed with eggshell it was the most effective out of the three varying binder forms that were used.
