摘要

Soil stabilization is influenced by various factors, primarily the properties of the soil and the use of cementitious materials. Soil chemical stability was evaluated via unconfined compressive strength (UCS), and characterization was performed using dynamic light scattering. An optimization study assessed the optimal quantities of cement and water needed for effective cementation with the incorporation of multi-walled carbon nanotubes (MWCNTs). The effect of MWCNTs on the strength and cementation of the mixture was evaluated. The UCS performance test showed that samples with 30% and 40% cement resisted disintegration, whereas those with less cement lacked structural integrity. Adding MWCNTs to the 40% cement sample increased the compressive strength to 94 kPa, while the sample with just 40% cement had a strength of 89 kPa. This study verified the effectiveness of incorporating MWCNTs into a chemically modified soil.
