PURPOSE: An alkali stimulant for improving physical properties of blast-furnace slag cement can increase a substitution rate of blast furnace slag up to 80% so that mobility and early strength improvement of blast-furnace slag cement can be enhanced. CONSTITUTION: An alkali stimulant for improving physical properties of blast-furnace slag cement includes calcium sulfate- silica sol powder of 25-83 weight% containing calcium ferri-aluminate (CFA) powder 5-45 weight%, sodium calcium sulfate (SCS) powder 12-45 weight%, calcium sulfate(CS), and Silica sol(SS). The blast-furnace slag cement contains granulated blast-furnace slag fine particle of 25-80 weight%, normal Portland cement of 19-72 weight%, and alkali stimulant of 0.1-3.0 weight% for improving physical properties of the blast-furnace slag cement.
