Behavior of Fly Ash at Different Mix Ratios with Plastic Recycled Polymers

Abstract

—: Fly ash is a waste produced from burning of coals in thermal power stations. The staggering increase in the production of fly ash and its disposal in an environment friendly manner is increasingly becoming a matter of global concern. Many efforts have been made to use the fly ash in various Geotechnical applications viz. embankment, roadway, railway, backfill material. In this study, plastic recycled polymers were mixed with fly ash at different mix ratios so as to inspect its influence on the geotechnical properties of fly ash. In this regard, the laboratory study includes Atterberg limits, Compaction characteristics, unconfined compressive strength, Direct shear test, Triaxial shear test and X-ray fluorescence test. Tests were carried out on only fly ash and treated fly ash with plastic recycled polymers. Results indicate increase in maximum dry density and also in shear parameters of the fly ash with inclusion of plastic recycled polymers.
