| Summary: | This research investigated the modification of stone column application by the association of PET plastic as a coarse
aggregate material for sustainable material replacement. Clay soil improvement with a granular material fabricated
column substantially affected its soil-bearing capacity. Subsequently, it avoided severe problems such as soil settlement
and structural instability. Previous studies have mentioned the function and alteration of stone columns using materials
like bottom ash and fly ash. Still, no attention has been paid to the utilization of PET plastic for this area. This study
examined the feasibility and reliability of materials, PET plastic, and kaolin clay S300 before examining geotechnical
properties through their physical and mechanical characteristics. The fundamental geotechnical tests verified that kaolin
clay was a problematic soil, and PET plastic was a substitute for coarse aggregate. Via the Unconfined Compression Test
(UCT) approach, the highest improvement magnitude of soil recorded was at 17.38kPa or 48.42%, referring to the
unreinforced kaolin specimen, which occurred at the GC10100 specimen. Coherently, it was suggested that the critical
column penetrating ratio was 1.0. The research proposed that using PET plastic could act as a reinforcing component to
rectify the engineering characteristics of kaolin. |
