Durability Performance of Soil Stabilized with Nano Additive's: A Review

Naturally occurring phenomenon such as freeze and thaw, wetting and drying, frost heave can significantly compromise the durability and water-resistant characteristics of soil. Over the last two decades, the geotechnical fraternity has sought to stabilize the problematic soil with the conventional additive's (cement and lime) and non-conventional additive's (fly ash, rice husk ash, slag, fibres, etc.). In recent years, there has been a growing interest in enhancing mechanical and durability behaviour of soil, the usage of nanoadditives, such as nanosilica, nanocopper, nanoalumina, nanocarbon fibres, nanocarbon tubes and nanoclay, is gaining popularity. This paper enlightens the published research work carried by various researchers on the durability performance of nanostabilized soil. The results indicate that nanotreated soil experiences reduction in strength as compared to natural soil subjected to durability cycles. From the review of the literature, it can be concluded that the inclusion of nanoadditives is helpful in improving the durability of soil.
