内容記述 |
Carbohydrate nanofibers (NF) derived from biomass waste exhibit superior mechanical characteristics and renewability, yet their potential for soil improvement remains largely unexplored. In this study, we systematically studied the soil reinforcement performance of 10–50 nm NF prepared from cellulose, carboxymethyl cellulose, chitosan, and chitin. Microscopic analysis revealed uniform dispersion of NF within the soil matrix without aggregation after soil treatment. Wet soil improvement efficiency by NF at 20 % moisture content varied largely between 0 % to ca. 100 % of the unconfined compressive strength (qu), showing the highest values for chitin NF of ca. 100 kPa. In contrast, 5 times strength improvement was achieved in dry conditions, reaching qu values up to 1.7 MPa. Covalent cross-linking and complexation with polymeric additives, which result in the formation of a biopolymer gel within the soil matrix, further increased the soil strength up to 2.5 times. However, comparison of soil improvement efficiency of NF dispersions and the corresponding water-soluble polymers, CMC and CS, showed that polymer-based treatment resulted in composites exhibiting ca. 50 % higher qu than NF-reinforced composites under identical conditions. The qu difference further increased to 150 % in the case of soil improvement by CS-CMC binary electrostatic networks compared to CSNF-CMCNF treatment. On the other hand, nanofibrillation enables the use of otherwise insoluble biopolymers such as cellulose and CT, showing comparable soil improvement characteristics with other types of NFs, expanding the scope of available renewable biomass materials for geotechnical and agricultural applications. |
