Abstract

The susceptibility of cohesionless soil to erosion has been a significant factor contributing to the failure of geotechnical infrastructure. This study aims to investigate the erosion resistance of zein biopolymer-treated sands. Cohesionless sand is used, and its index properties are determined. Treated specimens are prepared by mixing dry sands with 1% biopolymer content and compacted in transparent molds. Comparative analyses are conducted between the treated and untreated specimens using a hole erosion test, considering two hydraulic gradients. The results show that the erosion resistance of treated specimens significantly improves by up to 97% to 99% compared to the untreated specimens. The hydraulic shear stress and erosion rate decrease with the curing period, while erosion mass flux decreases with increasing hydraulic gradients. Curing periods and hydraulic gradients are significant factors influencing internal erosion. The findings demonstrate the potential of zein biopolymer as a novel method to enhance erosion resistance, suggesting its application in soil erosion control.
