Soil stabilization is a critical method for enhancing the mechanical and physical characteristics of weak soils to support construction requirements. This study explores the effectiveness of Rice Husk Ash (RHA) and Spent Catalyst RCC 15 (RCC) as environmentally friendly stabilizing agents. RHA, known for its high silica content and pozzolanic activity, and RCC 15, an industrial byproduct rich in silica, alumina, and iron, demonstrate considerable potential to improve soil strength and performance. Laboratory tests revealed that the best stabilization results were achieved with a mixture of 6% RHA and 11% RCC. This combination led to notable improvements, including an increase in maximum dry density (MDD), a reduction in optimum moisture content (OMC), and enhanced Atterberg limits. The Unconfined Compressive Strength (UCS) reached 2309 kg/cm², reflecting a 460,9% increase compared to the untreated soft clay, which had an initial UCS of 0,412 kg/cm². This substantial improvement highlights the effective pozzolanic reactions that occur between RHA and RCC, resulting in a denser and stronger soil matrix. By utilizing waste materials from agriculture and industry, the application of RHA and RCC 15 supports more sustainable construction practices, reduces reliance on conventional resources, and helps lower carbon emissions. These results affirm that the combination of RHA and RCC 15 is an innovative and sustainable solution for improving soft clay soils, contributing to the development of greener and more resilient infrastructure.
