Abstract

This work investigates the strength development of alkali activated blast furnace slag mortars (AAS) with tile dust (TD) at certain rates. BFS was used instead of cement at the rate of 60% and 80%. Sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) alkalis were added as solution into the mixture. First stage Na2O 6, 7 and 8 wt% of the BFS was added. Better results were obtained from the strength values of the sample containing 8% Na2O. Because of this result, in the second stage, tile dust was used instead of 5% and 10% of the BFS. However, silicate modules (MS = SiO2/Na2O) in both experimental studies were calculated as 0.5, 0.75 and 1.00. Twenty eight-days strength value of AAS+TD (tile dust was used instead of 5% and MS=0.75) specimen are higher than rate of 60% BFS specimen.
