| Abstract |
It has been increasing the demand of Eco-friendly materials which have low environmental effects and consume low energy. Such demands have led the study of alkali-activated ground granulated blast-furnace slag(AAG) mortar and concrete to be developing. In this study it was verified that 13 AAG mortar had been developed the compressive strength. 7 AAG mortar were set. Among them, sodium hydroxide and sodium silicate were shown high strength. So they were chosen to evaluate the compressive strength and the flow value of each contents. And sodium hydroxide or sodium silicate were mixed with another activators for improving performance. Compressive strength of AAG mortar with sodium hydroxide and sodium sulfate or sodium carbonate was increased as compared with AAG mortar using only sodium hydroxide. But setting time was decreased. AAG mortar with sodium silicate and sodium sulfate was improved performance of compressive strength and setting time. |
