The premix dry mortar was used as tile substrate mortar, tiling mortar, joint mortar for tiles and so forth. The granulated blastfurnace slag or the annealed blastfurnace slag could not use as fine aggregate for the premix dry mortar, because of the poor workability.<BR>In order to improve of the workability of mortar using the granulated blastfurnace slag as fine aggregate, a disintegration process was applied. The mortar tests using processed blastfurnace slag, non processed one and natural sand as fine aggregate were investigated. The workability of mortar using processed one was better than non processed one, and was similar to natural sand. Bending strength and compressive strength of mortar specimen were higher than non processed one and natural sand one. From these experiments, it was confirm that these processed blastfurnace slag could use as fine aggregate for the premix dry mortar.
