Effect of Saw Dust & Recron 3S Fibre on Index and Engineering Properties of the Landfill Soil

Landfill is a method of waste disposal utilizing soil in the elimination of discarded food, fibres and artifacts. About 2/3rd of landfill waste contains biodegradable organic matter from households, business and industries. Masses of waste product place in trenches or in soil encased mounds decay in a soil environment. Soil serves as a lining for the site, as cover, as a physical and chemical renovator. This has led to degradation of physical, chemical and strength characteristics of soil. This research work comprises of using saw dust and recron fibre to increase the soil characteristics. The aim was to increase the soil strength from waste materials. Index properties such as particle sieve analysis, water content, plastic limit, liquid limit and specific gravity were found for virgin soil and soil contaminated with saw dust (5%, 10%, 15%), recron 3s fibre (5%, 10%, 15%) & saw dust + recron fibre (10% + 10%). Experimental work includes Standard Proctor test, Direct Shear Test & permeability performed for Virgin Soil, Soil contaminated with saw dust (5%, 10%, 15%), recron 3s fibre (5%, 10%, 15%) & saw dust + recron fibre (10% + 10%).
