  • As a part of study to maximize the amount used of the ground granulated blast-furnace slag, the study deals with setting properties of paste that is mixed the ground granulated blast-furnace slag with CaO-Al2O3 based inorganic blinder. The results of the experiment show that the setting time is most fast in the mix of 25% rate of CaO-Al2O3 based inorganic blinder. It is generally needed 2 hours for work time in precast concrete products. In this study, this requirement is achieved when using the retarder of 0.5%.
