Investigation of the Effects of Recycled Materials and Natural Additives on the Stabilization of Fine-Grained Soils Using the Taguchi Optimization Method
Abstract
Increasing construction activities make it necessary to improve the engineering properties of fine-grained soils with low bearing capacity. In this context, the use of additives has emerged as a common and effective method for soil stabilization in geotechnical engineering. However, in recent years, the application of various experimental design and optimization methods to maximize the effectiveness of additives has become a remarkable trend. In this study, waste glass powder (WGP), basalt fiber (BF), rice husk ash (RHA), recycled carbon black (RCB), and lime (L) were selected as parameters to improve the properties of high plasticity clay (CH). The levels of these parameters were determined as follows: WGP (2%–8%), BF (0.25%–1%), RHA (5%–20%), RCB (1%–7%), and L (2%–8%). The optimum mixture ratios and the values of unconfined compressive strength (UCS) at 7 and 28 days were determined using the Taguchi Optimization Method. When the results obtained from the experiments were evaluated, it was determined that the most effective parameter on 7-day and 28-day unconfined compressive strength was lime. Furthermore, this research demonstrates that effective optimization of additives not only increases soil strength but also contributes to the integration of recycled materials into civil engineering applications.
