Abstract

Biopolymers have attracted a lot of attention from sustainable geotechnical engineering experts as of late due to their ability to improve soil mechanical characteristics. But there is a lack of information on how different biopolymers perform in healed soils in terms of their physico-mechanical characteristics. That is why this article treats Shanghai clay with biopolymers made of xanthan gum, chitosan, and guar gum. Compaction, unconfined compressive strength, and liquid-plastic limit tests are used to determine the fundamental physical qualities and biopolymer content of cured soils. Then, it talks about how various kinds of biopolymers affect these parameters. The order of increasing liquid
