Experimental Investigation of Expansive Soil Properties Stabilized by using Fly Ash, Waste Cement Bag Fiber, and Lime

The qualities of the soil on which the structure is made are primarily answerable for its instability. As an example, if the soil has poor index properties, cracking and settlement are possible. The structure of any road or pavement involves a variety of layers such as subgrade, subbase, base, and wearing course. The subgrade is critical in road construction. The current study is concerned with the improvement of soil properties by the accumulation of fly ash, waste cement bag fiber, and lime. Various proportions are 40% fly ash, 0.4% to 1.2% of waste cement bag fiber within the increment of 0.4%, and lime 0.9% to 2.7% within the increment of 0.9% by dry weight of soil sample to arrange the soil samples for stabilization. The tests which are Atterberg’s limit, Plasticity index, Specific gravity, Compaction test, California bearing ratio test, and unconfined compressive strength are performed to recognize the modifications within the properties of soil.
