Assessment of the Geotechnical Properties of Lateritic Soil Stabilized with Glass Powder as Partial Replacement of Cement. A Case Study of Ado-Ikere Road, Southwestern Nigeria

Abstract

The assessment of the properties of soil stabilized with glass powder as partial replacement of cement was investigated. Samples of lateritic soil were collected at varying depth from 0.5m into1.0m at a borrow pit along Ado Ikere road). The samples were air dried. Varying proportions of cement and glass power were used to prepare the mixture and these were expressed as percentage of the dry weight of soil sample. The results of these experiments showed that adding these additives resulted in a considerable reduction in the proportion of fine passing the various sieves in the grain size distribution study. These addictive substances were found in soil samples that were graded and classified properly. Furthermore, when these additives were used on soil samples, the results showed that the specific gravities were larger than in natural soil. The use of these chemicals resulted in lower C.B.R values in the samples than in the natural sample, according to the tests. Maximum dry density (MDD) decreased as the optimum moisture content was reduced, as evidenced by the compaction characteristic (OMC). The recommended value for cement soil stabilization with soil classification sand/gravel is B at 6%. Analysis of the additive showed Ca, Mg, Na and K. values which can be used as partial replacement materials in cement. The use of glass powder as a partial replacement for cement in soil stabilization was found to be ineffective in all geotechnical tests.
