| Abstract Scope |
This study presents the development and field application of concrete containing untreated bauxite residue (UBR) for heavy traffic pavements. Two construction techniques were implemented in a truck parking area: monolithic concrete slabs and interlocking paving blocks. Concrete mixtures were first optimized in the laboratory to ensure workability, pumpability, and mechanical performance. Subsequently, the materials were produced at an industrial scale and used in the construction of a 250 m² pavement area. Both field applications achieved the expected mechanical strengths. After five years of natural exposure, selected paving blocks were removed and tested. Results confirmed that the physical integrity was preserved, with no significant performance losses, and leached ion levels remained within safe limits, confirming the environmental safety of the concretes. These findings demonstrate not only the technical feasibility but also the long-term durability and environmental viability of using BR in large-scale concrete applications for infrastructure. |
