Members of the SICon research group published an article in the journal “Sustainability”, in the edition entitled “Building and Infrastructure Engineering: Sustainable Utilization of Innovative Eco-Efficient Materials”.
The article “Efficacy of the Simplex-Centroid Method for Optimization of Mixtures of Soil, Ladle Furnace Slag and Fly Ash Applied in Pavement Construction” is available as a publication submitted to the journal in the year 2024.
The research explores the use of industrial waste, specifically ladle furnace slag (LFS) and fly ash (FA), to stabilize two types of soil (clay and sand). Using a simplex-centroid experimental design, several mixtures were created and tested to evaluate the improvement in the mechanical properties of the soils. The tests revealed significant increases in compressive strength, CBR index and resilient modulus, with improvements of up to 130.5%, 324.4% and 132.6%, respectively. The best mixture was 80% soil and 20% LFS, without FA, which showed the best results in terms of mechanical resistance. The study suggests that the use of industrial waste is a viable and environmentally friendly solution to improve soil properties.
