Effect of Egg Shell Powder (ESP) on the Strength Properties of Cement-Stabilization on Olokoro Lateritic Soil

The effect of eggshell powder or ash on the strength properties of cement-stabilization on Olokoro lateritic soil was studied. The eggshell was mixed with the cement-stabilized soil in the proportions of 3%, 6%, 9%, 12% and 15% and the geotechnical behavior of the soil was carefully observed. The results of the study showed that the strength properties of the A-6 soil, according to its AASHTO classification, improved with the addition of eggshell ash. This also indicates that further addition of eggshell ash would thus; increase the strength properties of the stabilized soil further. However, eggshell ash has been established to be a good accelerator for cement-bound materials and this would be very vital for road construction work especially during the rainy seasons for minimizing the setting time of stabilized road pavements. The study also exposes the engineering value of this agricultural material which probably causes disposal problems, leading to environmental pollution.
