This study aimed to produce environmentally friendly and economical mortars by using various waste lime resources instead of lime in gypsum-lime-pozzolan ternary mortars. With the use of waste lime resources, both the wastes will be evaluated, and the natural lime resources will be conserved. As waste lime sources, Af & scedil;in-Elbistan fly ash, sugar factory filter cake, and colemanite triage waste were used at the rates of 10%, 20%, and 30%. The pozzolans used in the ternary mixtures were fly ash, metakaolin, and rice husk ash. Unit weight, porosity, water absorption, capillary water absorption, ultrasound pulse velocity, compressive strength, flexural strength tests and XRD, TGA, and SEM analyses were conducted on the produced mortars. The results showed that a substantial part of the samples containing waste additives exhibited lower strengths than the reference samples. RHA showed the lowest unit weight and highest porosity, while MK achieved the highest compressive strength. The use of 30% AEFA notably improved water absorption and flexural strength. However, the values obtained were considered to meet the minimum requirements specified in the standards for masonry mortars and gypsum plasters.
