Abstract

This paper presented the design of a composite grinding aid for steel slag and granulated blast-furnace slag with glycerol distilled residue as main raw material. Several commonly used grinding aids were investigated and the optimal formulation of the composite grinding aid was obtained with the mass ratio of triethanolamine: glycerol: calcium lignosulfonate: glycerol distilled residue =1:1:5:3. The suitable dosage was 0.03 % of the material to be ground. The steel slag and granulated blast-furnace slag powders ground with this composite grinding aid gave higher fineness and the cementing material produced exhibits higher mechanical strength at any age, indicating that there is a synergistic effect among the materials used.
