Effects of Preparation’s Parameters on Stabilization of Sabodala Gold Mine Tailings: Comparison of Fresh and Weathered Materials

Autor: Ibrahima Dia, Mababa Diagne, CheikhIbrahima Faye, Mamadou Gueye, Dame Keinde

Publikováno v: Journal of Geoscience and Environment Protection. :21-35

The Sabodala gold mine tailings were stabilised using geopolymerization technics in order to improve their mechanical properties in general for a reuse as building materials for local communities. The effect of several preparation parameters on the c
