The Role of Nanoclay in the Soil Stabilization: A Short Viewpoint

Abstract

Nanoclay, composed of phyllosilicates, exhibits unique properties due to its layered structure and its ability to swell or shrink in response to water accumulation or withdrawal. Its use in geostability involves enhancing the geotechnical properties of soils, such as reducing the plasticity index, increasing specific gravity, improving compaction, and enhancing shear strength. Additionally, nanoclay serves as a reinforcing material in polymer composites, improving their strength, toughness, durability, and barrier properties. This study provides an overview of the properties, applications, and challenges associated with nanoclay in soil stabilization. The compatibility of nanoclay with organic monomers and polymers can be modified to enhance the overall performance of nanocomposite materials. Various industries and applications utilize nanoclay for soil stabilization, including construction, agriculture, mining, and environmental remediation. However, there are challenges associated with its use, such as cost, compatibility with different soil types and stabilizers, environmental concerns, long-term durability, and health and safety risks. Future research should focus on the synthesis, characterization, and surface modification of nanoclay, as well as the effectiveness of different soil stabilization methods and potential environmental impacts.
