Soil Stabilization Using Zein Biopolymer

The characterization and analysis of the cementation properties novel biopolymer binders in soils are essential for their potential application geotechnical engineering. This study investigates effect a zein binder on sandy soils. Soil specimens mixed with various contents ranging from 0 to 5%. mechanical microscopic characteristics treated evaluated using unconfined compression tests scanning electron microscopy, respectively, after curing 3, 7, 28 days. results show consistent increase compressive strength elastic modulus increasing periods contents. A small amount (1%) increases soil elasticity regardless gradation. Additionally, bonding force between soil–zein linearly uniformity. Therefore, can be potentially used as fine- coarse-grained engineering considering its stabilization sustainability properties.
