Abstract
Stabilization of clayey soil with an inadequate physical and mechanical properties in its natural state represents one of the actual challenges in contemporary geotechnical engineering. Among numerous stabilization techniques, chemical stabilization stands out as an effective technique for stabilizing clayey soils. By applying this technique, various types of stabilizers may be used, whereby they react with soil particles and modify its structure, contributing to the permanent improvement of the physical and mechanical properties of the soil. In this study, waste materials obtained as a product of industrial processes, such as fly ash and rock flour, were considered as chemical stabilizers. A comparative analysis of the effects of adding fly ash and rock flour on improving the uniaxial compressive strength (UCS) and the shear strength parameters of clayey soil was performed, while simultaneously monitoring the durability of the achieved effects.
