Waste Management and Application of Waste Micro-Sized Palm Kernel Shell Ash (MSPKSA) in the Stabilization of Engineering Soil

Onyelowe KC and Maduabuchi MN

The management of solid waste and the application of Palm Kernel Shell Ash in the stabilization of Umuntu Olokoro lateritic soil for construction purposes were studied. The waste PKSA was mixed with the stabilized soil in the proportions of 3%, 6%, 9%, 12% and 15% and the behavior of the soil observed for its Geotechnical properties. The results of the study showed that the strength properties of the A-2-7 soil improved with the addition of waste PKSA. The indication is such that further addition of the waste would increase the strength properties further. Waste management and disposal which has posed a big problem for the southeastern states of Nigeria has, by the results of the work received a boost in that disposal of waste; palm kernel shell would now be beneficial to the works ministry for use as admixture in the stabilization and improvement of soil for road construction purposes. So, we call on the works and environment Ministries to collaborate in the task of Geowaste management of the area to save our environment from the hazards of dumping palm kernel shell and the pavement facilities.
