ABSTRACT

This research analyzes the impact of the incorporation of marble filler and sugarcane ash in the stabilization of tropical soils, specifically in the Central Peruvian rainforest. These soils, characterized by their high plasticity and low bearing capacity, represent a significant challenge for civil engineering. Four proportions of marble filler (3%, 6%, 9% and 12%) and sugar cane ash (1%, 2%, 3% and 4%) are evaluated in order to determine the optimum combination to improve soil strength and stability. The tests performed included granulometric analysis, determination of the plasticity index, consistency limits and mechanical property tests, such as the modified Proctor compaction tests and the CBR index. The results reveal that the combination of 6% marble filler and 2% sugarcane ash improves the bearing capacity and reduces the plasticity of the soil, obtaining a plasticity limit of 9.44%, a modified Proctor of 2.112 kg/m³ and a CBR of 13.57%. This approach, which takes advantage of industrial and agricultural by-products, represents a sustainable and economical alternative for soil stabilization in regions with similar characteristics, providing a viable solution for infrastructure development in areas with soils of complex properties.
