Abstract
The carbonate bonding process consists of mixing a suitable material with water and lime hydrate, compacting the mixture, and reacting it with carbon dioxide-rich gas to form a coherent structure bonded by a matrix of calcite crystals. A laboratory study has indicated that taconite tailings could be carbonate bonded to form an effective road paving or brick-making material. In general, the compressive strength of carbonate bonded taconite tailings increased with increasing lime hydrate content, reaction time, and carbon dioxide concentration in the reaction gas. In addition, air and water permeabilities, freeze-thaw resistance, and flexural strengths of carbonate bonded taconite tailings were found to be comparable to concrete. Scale-up of the laboratory studies to demonstrate paving applications in small plots was hampered by a failure to obtain sufficient compaction. The results, however, did confirm the laboratory study findings. (Modified author abstract)
