An Experimental Study On The Impact Of Nanomaterials And Biopolymers On Cohesive Soil

Abstract

All around the world, cohesive soils can seriously damage buildings and infrastructure. Many novel techniques are now being explored to increase the cohesive soils' strength in an effort to reduce their unwanted qualities and make them appropriate for building. Biopolymers, such as plant mucilage and microbial extracellular polymeric substances, are produced in near-surface soils by living organisms and provide improved moisture retention and protection from dry environments. They also lubricate roots to enable root penetration through soil and physically connect soil grains to form soil aggregates. The area of soil improvement has benefited from the availability of novel materials in addition to conventional procedures. The most novel concepts in soil stabilisation that have been developed recently are the addition of nanomaterial and biopolymers. For soil stabilisation, microbially induced polymers, also known as biopolymers, are added with the intention of reducing environmental contamination. Geotechnical engineering uses nanotechnology in two ways: first, it can be used to observe the structure of soil at the Nano scale, and second, it can be used to manipulate soil at the atomic and molecular levels. This study examines the viability of using biopolymers and nanomaterial to stabilise cohesive soil and analyses the resulting change in geotechnical parameters. Tests were conducted to identify the ideal proportion and strength features of additions, which included adding powdered tamarind kernel and nano-silica to soil at different percentages (0, 0.25%, 0.5%, 0.75%, and 1%).
