Performance Evaluation of Ternary Blended Alkali-Activated Mortars Incorporated with Industrial Waste Byproducts—A Step Toward Sustainability

Alkali-activated material is a new material that can produce alternative construction materials with a lower carbon footprint. This research focuses on performance of ceramic tile waste dust (CTWD) as a new precursor for developing alkali-activated mortars (AAMs). Ternary blended AAMs comprised a mix of CTWD, fly ash, and ground granulated blast-furnace slag, whereas the CTWD content varied between 10 and 50 wt.%. After the test results analysis, mortars elaborated with the CTWD showed decreased mechanical properties as the CTWD content increased. The optimal formulation included 10% CTWD, 10% fly ash, and 50% GGBS, reaching 58 MPa at 28 days. From this study, AAMs show good workability and final setting time incorporating CTWD. The use of waste industrial byproducts in AAMs will reduce the load on environmental and helps in achieving sustainability and its optimum use.
