Utilizing Recycled Rubber and Municipal Waste Incineration Fly Ash in Cement-Stabilized Clayey Soils

This study explores an innovative approach combining municipal solid waste incinerator fly ash (MSWIFA), cement, and recycled rubber to enhance soil properties. The research fills a research gap by exploring the synergistic effects of these materials, striving to strike a balance between strength and flexibility in soil stabilization. A total of ۱۲۳ tests, comprising Proctor compaction and unconfined compression tests, were performed on clayey soil samples treated with varying stabilizer proportions: ۱۰%, ۲۰%, and ۳۰% MSWIFA; ۱۰%, ۱۵%, and ۲۰% cement; and ۰%, ۵%, and ۱۰% rubber by dry weight. The tests revealed that the ideal blend of ۵% rubber, ۱۰% MSWIFA, and ۲۰% cement resulted in a notable ۲۹۴% increase in unconfined compressive strength and a significant enhancement in soil ductility, presenting a stark contrast to traditional cement-stabilized soils recognized for their brittleness and limited flexibility. This approach not only enhances soil characteristics but also promotes environmental sustainability by utilizing waste materials in the stabilization process. Doi: ۱۰.۲۸۹۹۱/CEJ-۲۰۲۴-۰۱۰-۱۱-۰۱۷ Full Text: PDF
