Properties of Sand Grout with Iron Ore Tailings as Fine Aggregate
Innovative researches on properties of sand grout with iron ore tailings (IOT) as fine aggregate were conducted. The results show that exclusive ferrous mineral in the IOT is merrihueite beside quartz in both IOT and nature sand (NS). IOT have similar thermal stability with NS. Sand grout with IOT has higher compressive strengths resulted from existence of ferrous minerals and more complex morphology of particles. However, size shrinkage of the sand grout slightly increases to 0.09% of initial testing specimen. It is feasible that IOT as fine aggregate can be used to produce sand grout.
