Abstract
Soil is a complex material composed essentially of clay minerals and sand with organic and associated minerals which influence soil properties. The purpose of this study is to identify the potential of compacted soil as an alternative material in construction by replacing concrete for retaining walls or foundation structure. The materials that have been used in this study were categorized as the main groups of crystalline materials of clay that is called kaolinite. The specific gravity test result showed 2.6 Gs, which categorizes the soil into the kaolinite group. Besides, this material improved the soil characteristics by compaction with the optimum moisture content using the standard Proctor test. The result from the standard Proctor test is determined by the ratio of soil mass to the maximum water content in the soil, with the achieved ratio being 5.5 kg of soil to :920 ml of water in this case. The result from the unconfined compressive strength test was 78 kN/m2, which shows medium consistency of kaolinite, thus showing a good prospective for it to replace concrete in columns. In addition, the material is also compared with residual soil as another alternative for contact with cold-formed steel sections. The different values of specific gravity and unconfined compressive strength are recorded as 0.11 and 226 kN/m2, respectively. It also illustrated that kaolinite has a potential for contact with or to fill in cold-formed steel columns.
