The Application of Blast Furnace Slag in Cementitious Self-Leveling Mortar
This article presents a study on the adequate application of blast furnace slag to replace quartz sand in cementitious self-leveling mortar. The results show that the strength of mortar decreases slightly, because slag sand can drag in some air bubbles which can form holes in the harden mortar. And compared with quartz sand, its compression strength loses only 4.6 % on 28d age. the proportion of 75 % slag sand and 25 % quartz sand was the best proportion as coarse filler.
