Estimating the mechanical properties of soil samples involves analysing properties such as shear strength, density, and moisture content. It is important to use consistent and standardized testing methods, as well as to normalize the data to the same volume or weight, when comparing soil mechanical properties. Evaluating multiple properties will provide a more complete understanding of the differences between soils. Additionally, it is crucial to consider factors such as soil composition, history, and location when comparing soil properties. The main purpose of this paper is to compare the two types of soil which are waste soil and clay soil. Waste soil tends to have weak structure due to the multiple content of waste while clay soil is weak because of water absorption of in the clay structure. These two properties will have implications in terms of its mechanical properties. The experimental works that was conducted in this research are direct shear stress, density, water content and compressive strength. Clay soils tend to be less dense due to their fine-grained nature and the small size of their particles. Waste soil, on the other hand, can vary in density and can often be less dense than natural soils due to the presence of large void spaces. The water content in clay soils can significantly affect its shear strength, as excessive water can weaken the cohesive forces between the clay particles. In waste soil, the moisture content can affect the density and compaction of the soil, which can impact its stability. The expected outcome from this research is the conclusion of the mechanical properties for both types of soil.
