EXPERIMENTAL ANALYSIS ON STABILITY OF EXPANSIVE SOIL BY PARTIAL REPLACEMENT OF EGG SHELL POWDER AND POWDERED GLASS

Soil is one of the most important materials used in a variety of construction projects including earth canals and earth dams. Nowadays, considerable attention has been paid to the utilization of alternative materials, which bear higher engineering quality than traditional materials and are financially affordable. In the present study, eggshell powder and glass powder were used as the wastes, to combine with soil so that the properties of clay soil were investigated in different mixture proportions. Then the properties of soils including liquid and plasticity limits as well as plasticity index, dry density, optimum moisture content and unconfined compressive strength, which were already measured, were compared with those of the experimental specimens mixed with eggshell powder and glass powder in different proportions. Since the introduction of egg shell powder and glass powder improves the engineering behaviour of soils, also make the glass powder and egg shell powder a good replacement or admixture during soil improvement and for a more economic approach.
