FROST RESISTANCE OF MASONRY MORTAR BLENDED WITH INDUSTRY AND AGRICULTURAL WASTE

The use of waste materials in masonry mortars is not common, as traditional mortars primarily rely on cement and lime as binders. This study aims to investigate the effect of replacing cement with locally available industrial and agricultural waste materials: ceramic waste powder, corn cob ash, and fly as, on the frost resistance of mortar. As part of the experimental investigation, eight different mortar mixtures were prepared, varying the volume ratios of solid components (cement:lime:sand = 1:0.7:4.2 and 1:1:4), with cement being replaced by waste materials up to 50%. Since the mortars retained 75% of their initial compressive strength after 25 freeze-thaw cycles, it has been demonstrated that the selected materials can be successfully used in innovative and more environmentally friendly masonry mortars in low-temperature environments.
