<p>The article analyzes the possibility of using two types of waste from the thermal transformation of municipal waste in the production technology of cement mortars. Fly ash and dust were used in amounts of 5, 10, 15, 20, 25 and 30% of the cement mass as a replacement for sand. In total, 11 series of cement mortars were prepared: a standard control mortar and 10 series of mortars modified with individual waste. The following tests were performed for the prepared samples: bending and compressive strength after 7 and 28 days of maturing, water absorption and consistency testing for fresh mortars. Based on the results obtained, it can be concluded that the use of waste dust and fly ash in the amount of 30% as a replacement for sand reduces the compressive strength by 24.0% and 8.0%, respectively, and the bending strength by 23.6% and 21.5%, respectively.</p>
