This investigation aims to examine the behavior of natural and manufactured pozzolans, as well as the properties of blended mortars. Eco-friendly building materials are gaining the attention of researchers worldwide, as they are made from supplementary cementitious materials that alter the fresh and mechanical properties of the blended mortar. Granulated blast furnace slag, silica fume, zeolite powder, metakaolin, clay powder, fly ash, rice husk ash, copper slag, and glass powder have all been used to improve the microstructure, workability, setting time, and strength. The control mixes contain a range of replacement rates (5–50 %) as supplementary cementitious materials compared to the OPC reference mortar. Brick clay powder (5–15 %), Granulated Blast Furnace Slag (5–20 %), Silica Fume (5–25 %), Copper Slag (5–35 %), Metakaolin (5–25 %), Fly Ash (5–30 %), Rice Husk Ash (5–20 %), Zeolite Powder (5–20 %), Ceramic Waste (5–35 %) and Glass Powder (5–10 %) were identified as the beneficial proportion. Moreover, strength increases simultaneously with the volume/index of the big content of all supplementary cementitious materials blends, but beyond the critical level of supplementary cementitious materials mixes, it tends to reduce strength. The changes made by integrating supplementary cementitious materials are significant in terms of both the fresh and hardened properties of blended mortar.
