Improvement of Properties of Expansive Soil using Terrazyme
Abstract: Enzymatic emulsions contain enzymes that react with soil molecules to form a cementing bond that stabilizes the soil structure and reduces the soil’s affinity for water. When the bio-enzymes like Terrazyme, are mixed with soil they alter its engineering properties. When added to a soil, the enzymes increases the wetting and bonding capacity of the soil particles and improves the chemical bonding between soil particles and creating a more permanent …

Effect of Improvement of Collapsible Soils with Bitumen Emulsions on Collapsibility Rate for Varying Degrees of Saturation
Abstract: Collapsible soils are one of many problematic soils in Iraq. Many foundation failure problems that occurred in Iraq are associated with percolation of water; the change in the degree of saturation can affect the stability of these soils and may encounter large volumetric change. A series of tests conducted on collapsible soil using oedometer apparatus and the settlement–time curves are determined accurately, then each test is determined to a different …

Stabilization of Alluvial Soil by using Boiler Feed Ash
Abstract: The feasibility of using industrial wastes, boiler feed ash (BFA) (rice husk-based) from an oil mill for soil stabilization was studied. The waste material is produced as an industrial by-product in the boiler of the oil mill; the waste contains silica compound up to 85%, hence it can be used as a stabilizing agent. The effects of adding BFA on Proctor's density, Atterberg’s limits, soil plasticity and the CBR value …

Comparative Study on Stabilization of Expansive Soil using Cement Kiln Dust and Ceramic Dust
Abstract: In India, expansive soils cover about 20% of total land area, these soils increase in volume (swell) during winter season and decrease in volume (shrink) during summer season. Due to this contradiction behaviour many civil engineering structures constructed on expansive soils get damaged severely, out of which pavement is the most because they are lightweight and extend over large areas. Stabilization of Expansive soil is of most importance, since to …
