Expansive soils pose geotechnical challenges due to volumetric changes in the presence of water, being common in the region of Pelotas/RS. This study evaluates the efficiency of different stabilizing agents — lime, Construction and Demolition Waste (CDW), and natural Butia fibers — in mitigating the expansiveness of a clayey soil. The methodology is based on the MCT (Miniature Compacted Tropical) method, analyzing water penetration and diametrical shrinkage of specimens molded with different additive contents. Previous results indicate that lime shows superior performance in delaying the wet front, while CDW acts as a filler material with limitations as a primary stabilizer. The inclusion of Butia fibers (BF) proposes a sustainable mechanical reinforcement mechanism, aiming to reduce cracking and improve dimensional stability. This work contributes to the development of low-environmental impact solutions by comparing traditional methods and innovations based on regional biodiversity.
