- Abstract
Three gradations of fine iron tailings are selected to prepared surface mortar for external thermal insulation on outer-walls for replacing natural sand. The working performance and mechanical performance of the surface mortar for external thermal insulation on outer-walls are studied. The results show that the water requirements of surface mortar for external thermal insulation on outer-walls is almost no difference at same consistency when the dosage of 0-0.1mm, 0.1-0.3mm and 0.3-0.5mm fine iron tailings is respectively below 80g/kg, 100g/kg, 150g/kg, and the flexural strength, compressive strength and tensile adhesive strength at 28d of surface mortar for external thermal insulation on outer-walls is higher than it prepared natural sand. The water requirements of surface mortar for external thermal insulation on outer-walls prepared by fine iron tailings instead of all natural sand is 24% higher than it by prepared natural sand, the flexural strength, compressive strength and tensile adhesive strength at 28d of surface mortar for external thermal insulation on outer-walls is slightly lower than it prepared by natural sand. The working performance and mechanical performance of the surface mortar for external thermal insulation on outer-walls by fine iron tailings instead of all natural sand can meet requirements of JC/T 2084-2011.
