Abstract:With occasional disruptions in the supply of quality fly ash, and the global move towards sustainable means of power generation, it is timely for the Australian construction industry to examine the use of alternative Supplementary Cementitious Materials (SCM's) in various concrete applications. In this study, Metakaolin, Ground Granulated Blast Furnace Slag and Fly Ash were used to partially replace traditional Portland cement in mortar mixtures. The influence of these SCM's on the workability and early age strength development of mortars was examined, along with their effectiveness in mitigating the alkali-silica reactivity (ASR) of aggregates, which was evaluated using the new Australian Standard ((AS1141.60.1) (1)) for the Accelerated Mortar Bar Test (AMBT). Both the type and dosage of the two SCM's were studied.
