Green Stabilization of Bauxite Tailings: Mechanical Study on Alkali-Activated Materials
This study evaluates the alkali activation of a binary system composed of sugar cane bagasse ash and carbide lime as a green stabilization technique for bauxite tailings (BTs). To analyze the feasibility of this alternative binder as a stabilizer, mechanical tests were performed to measure the strength, stiffness, and durability of BT binder mixtures. As a control group, tailings were stabilized with high-initial-strength portland cement (Type III). The results show that the alternative binder is a suitable option to improve the mechanical behavior of bauxite tailings. The porosity/binder index () was an appropriate parameter for evaluating BT stabilization. Reduced porosity and increased binder content (decreased ) led to an improvement in the mechanical behavior of the studied mixtures.
