Abstract: The present study attempts a detailed investigation on the strength performances of alkali activated concrete (AAC) mixes incorporating slag, fly ash, and powdered waste glass as binding ingredients for structural masonry applications. All the concrete mixes were prepared by using graded stone crusher dust as fine aggregates. The tests were performed to investigate the mechanical strength performances, and the results were compared with the conventional OPC-based blocks. Tests were also extended to investigate the effect of one type of geogrid reinforcement on the strength performances of AAC masonry blocks. The prism strength and the cost analysis of the conventional and AAC masonry blocks were also carried out. All the test results strongly prove that the alkali-activated masonry blocks are comparatively better than the conventional blocks made up of OPC. Thus, the use of AAC blocks can be highly recommended as a sustainable alternative to traditional OPC structural masonry executions.
