Use of Mining Tailings for the Stabilization of Clay Soils
A study evaluated the use of inert mining tailings to stabilize clay soils with low bearing capacity, comparing different dosages and mixtures with tailings-cement mortar. The alternative with 15% tailings-cement mortar showed the best performance, increasing the CBR from 5.1% to 15.4% and significantly improving the soil’s mechanical strength. The results demonstrate the potential for reusing mining tailings in geotechnical applications, promoting the circular economy and sustainable solutions for road subgrade stabilization.
