Performance Evaluation of Polysachharide based Biomaterials for Sand Stabilization

Abstract

Recent research on soil improvement have showed that the use of biopolymers can significantly enhance the various engineering properties of the soil. Soil improvement using biopolymers has attracted considerable attention in recent years, with the aim to reduce the harmful environmental effects of traditional materials. This report aims to provide a review on the environmental assessment of biopolymers as binders in soil improvement, biopolymer-treated with soil characteristics, as well as the most important factors affecting the behavior of the treated soil. Various geotechnical properties are evaluated and compared, including the unconfined compressive strength, and durability of biopolymer-treated soils. The usage of biopolymers has positive effects on the soil in the form of enhanced strength, However, a thorough understanding of the geotechnical qualities is required in order to completely apply the biopolymer technology to the fields. Biopolymer kinds, soil types, biopolymer contents, curing times, thermal treatment, and mixing techniques all play a significant role in how effective biopolymers are at improving the ground. In this part of study, the pycnometer method, sieve analysis, standard proctor compaction tests, unconfined compression test, durability, gel plug tests, pH test, and FTIR test, were used to understand and analyze the pectin-treated sand.
