Evaluating the effectiveness of the Nicoflok polymer-mineral additive in soil reinforcement

This study investigates the effect of the Nicoflok polymer–mineral additive on the strength and durability of stabilized soils used in transport foundation layers. The research aims to enhance the structural performance and longevity of roadbed materials under varying climatic conditions typical for Uzbekistan. Laboratory tests, including compressive and flexural strength, water absorption, and density measurements, were conducted on samples containing different proportions of Nicoflok. The results indicate that the additive significantly improves the mechanical stability and reduces the moisture sensitivity of cement–soil composites. Statistical analysis with confidence intervals confirmed the reliability of the findings. The novelty of this work lies in the systematic evaluation of Nicoflok’s efficiency for soil reinforcement within the Central Asian context, where such polymer-mineral systems have not been previously studied.
