The article presents the physico-mechanical properties of cement mortars modified with addition fly ash generated from municipal waste incineration (MSWI-FA) and dust rotary kiln dedusting installations (CKD—cement dust) produced during manufacturing. materials were dosed separately in combination—MSWI-FA amounts 10, 15, 20% mass, a volumetric adjustment standard sand while CKD was used as replacement mass. Basic tests conducted on prepared mortars, including consistency flexural compressive strength after 7 28 days curing, water absorption, bulk density, resistance to freeze–thaw cycles. results indicate that MSWI-FA reduces compared control series, proving be more effective stable than MSWI-FA, especially over longer curing periods. combination often resulted greatest decline mechanical parameters, suggesting limited synergy between these materials. best achieved using low additive concentrations, MSWI-FA-CKD/3–3 (i.e., 3% waste) combination. research confirms potential utilizing sustainable compositions but highlights need for further work optimizing proportions modification techniques. importance efforts reducing environmental impact promoting circular economy is emphasized.
