ABSTRACT

This research looked into the effect of glass powder as partial replacement of cement on the geotechnical properties of silty soil. The waste glass was grinded to powder and choose as a partial replacement of cement with a view to obtaining suitable percentage of the glass powder that can partially replace cement and still provide the soil with the adequate engineering properties required to make it useful in the construction industry. The soil sample used was collected from the Federal Polytechnic Ado-Ekiti and was subjected to laboratory tests in other to classify the soil. The soil sample was stabilized with 10% additive(s) by weight of the soil sample. Since the goal is to partially replace cement with glass powder, the quantity of cement used was been reduced in steps of 2% and replaced by glass powder to give the total sum of 10% additives. The effects of this alteration were monitored on the consistency limits and compaction tests. The consistency limits results revealed that 8% replacement of cement by glass powder increases the plasticity of the soil as the Plasticity Index moves from 18.03% in 10% cement to 21.69%. The compaction results showed that 6% replacement of cement by glass powder increases the soil?s Maximum Dry Density and Optimum Moisture Content from 1509Kg/m3 to 1748Kg/m3 and 12.8% to 17.4% respectively as compare to 10% cement. The results proved glass powder to be suitable as replacing material for cement in stabilization of soil.
