Unconfined Compression Strength of Reinforced Clays with Carpet Waste Fibers

Laboratory evaluation on the effectiveness of polypropylene fibers on the strength of fiber-reinforced and cement-stabilized Shanghai soft clay

“…Poor durability is furthermore a shortcoming of cementeclay stabilized materials. Utilizing tensile elements, such as fibers and fiber bundles to improve the tensile strength and the flexural strength, has the advantage of improving the strength and durability of improved soil and will furthermore be effective because of its strength isotropy, absence of potential failure plane, improvement in peak friction angle and cohesion, environmentally savings and economical cost (Kaniraj and Havanagi, 2001;Sobhan and Mashnad, 2002;Yetimoglu et al, 2005;Kumar et al, 2006;Viswanadham et al, 2009;Park, 2011;Hejazi et al, 2012;Mirzababaei et al, 2012;Onyejekwe and Ghataora, 2014;Jamsawang et al, 2014). Several past studies have proved the effectiveness of polymer fiber reinforcement in treating cemented soft soil and provided experimental evidence on the improvement in its mechanical behavior (Li et al, 1995;Kaniraj and Gayathri, 2003;Tang et al, 2007;Park, 2009;Noorzad and Mirmoradi, 2010;Tang and Gu, 2011).…”

Consistency limits and compaction characteristics of clay soils containing rubber waste

“…Promising replacements, based on recent studies, include recycled tyre rubbers, waste textiles, demolition wastes, kiln and quarry dusts, and silicate/calcium geopolymers (e.g. Al-Amoudi et al, 2017;Alazigha et al, 2016;Arulrajah et al, 2017;Kua et al, 2017;Mirzababaei et al, 2013aMirzababaei et al, , 2013bSoosan et al, 2005).…”

Discussion of “Compaction and Strength Behavior of Tire Crumbles–Fly Ash Mixed with Clay” by Akash Priyadarshee, Arvind Kumar, Deepak Gupta, and Pankaj Pushkarna

“…(1). Most strength-related soil stabilization problems involving two independent variables exhibit nonlinearity or curvature (e.g., Mirzababaei et al 2013;Olgun 2013;Soltani Forthcoming), and thus can be efficiently represented by the multiple quadratic regression (MQR) model. For the problem at hand, a suitable MQR model can be expressed as…”
