High-calcium low-silicon type copper tailing admixture, copper tailing-based cement mortar and preparation methods of high-calcium low-silicon type copper tailing admixture and copper tailing-based cement mortar
The embodiment of the invention provides a high-calcium and low-silicon type copper tailing admixture, copper tailing-based cement mortar and a preparation method. The admixture comprises 98-99.5 wt% of high-calcium and low-silicon type copper tailings, 0.5-1.5 wt% of a high-calcium and low-silicon type cement mortar and 0.5-1.5 wt% of a high-calcium and low-silicon type cement mortar, 0.2 to 1 wt% of a water reducing agent; 0.3 to 1 wt% of an alkaline activator; the high-calcium low-silicon type copper tailings comprise 20 to 30 weight percent of SiO2, 18 to 30 weight percent of CaO, 15 to 25 weight percent of Fe2O3, 4 to 7 weight percent of Al2O3, 2 to 4 weight percent of MgO, 1 to 2 weight percent of K2O + Na2O and 15 to 30 weight percent of LOI; the specific surface area of the high-calcium low-silicon copper tailings is greater than 500m < 2 >/kg; particles with the particle size smaller than 80 microns in the high-calcium low-silicon type copper tailings account for 90% or above. A new thought is provided for resource utilization of the high-calcium low-silicon type copper tailings, and a solution is provided for bulk utilization of the high-calcium low-silicon type copper tailings.
