Suitability of Rupganj Soil for Earth Construction

Abstract

In order to use the soil as a construction material for earth construction, we need to check the suitability of the said soil. For which, its geotechnical properties are required to be examined. The purpose of this study was to determine the suitability of Rupganj soil by reviewing previous studies on the suitability criteria and previously published similar soil samples. This study was conducted under the main reference of a previous review paper which compiled the necessary information and requirements for a soil to be deemed suitable for earth construction. We have conducted the study on 7 soil samples from different depths of the similar area and assessed them according to the chosen criteria. Five geotechnical properties were compiled and referred to and then analyzed. These properties are particle size distribution, specific gravity, maximum dry density, optimum moisture content and Atterberg limit. Based on the values of soil properties found on the literature review, and other recommendations from previous studies, analysis was carried out and recommendations were made for the suitability of different samples. We have also analyzed the cost and environmental impact produced by the suggested soil methods. It was noted that some of the soil samples passed one set of criteria while failing the others. For this, stabilization techniques and materials were suggested. Finally, the study concludes whether the soil of said region is suitable for earth construction, and if not then what methods need to be applied.
