One of the most common approaches to dealing with problematic soils is stabilization, which aims to lessen their unfavourable characteristics. Cement and lime, which have excellent strength properties, are often employed in soil improvement projects. However, they require much energy to manufacture and contribute to worldwide CO2 emissions. In order to mitigate the adverse effects caused by cement and lime, sustainable stabilizers must be developed from nontraditional sources like waste and by-products. The primary goal of the study was to examine the viability of using Ceramic Dust (CD), an industrial by-product, as a soil stabilizer, on its own or in combination with Hydrated Lime (L), Ordinary Portland Cement (OPC), or Ground Granulated Blast Furnace Slag (GGBS). This study examined the stabilizer`s engineering characteristics by conducting laboratory experiments such as Atterberg limits, Standard Proctor Compaction, Unconfined Compressive Strength (UCS), linear expansion (LE), durability, California Bearing Ratio (CBR), and permeability. During the preliminary stage of the research, compacted cylinders of laterite soil (LS) stabilized with primary stabilizers, denoted as S1L, S1P, S1G, and S1C; secondary stabilizers of S2L and S2P; and tertiary stabilizers of S3L and S3P were fabricated.
