Making environmentally friendly, long-lasting roller compacted concrete (RCC) was the primary focus of the laboratory experiments using disposed waste material (demolished buildings) and lowering the amount of fine aggregate adopting the ACI 327. The best way to dispose waste materials of demolished buildings such as ceramic tiles, clay bricks, and thermostone hollow blocks without using a sanitary landfill was to collect them, crush them with a crushing machine, and grade them by sieving to a fine aggregate. Reference mixture (RM) and six other environmentally friendly, long-lasting RCC mixtures were produced with partial fine aggregate volume replacements of 10 and 20% waste material. Following the production of the mixtures, the strength (compressive, splitting tensile, and flexural), porosity, absorption of water, and dry density were all tested. The results in accordance with the study’s conclusions are the RCC containing (20%) by ceramic tiles as fine aggregate increases RCC’s durability up to (5.76%) (2.96%) (2.83%) of strength (compressive, splitting tensile and flexural) at 28 days of testing, in opposition to the typical blend, then the blend that includes (10%) of ceramic tiles as fine aggregate with % growth up to (3.39%) (1.64%) (1.42%). While the clay bricks with 10% can be adopted, the results were slightly lower than the RM but still in the specification range (minimum recommendation of ACI 327 = 28 MPa). For the mixtures with 10 and 20% thermostone blocks fine aggregate, the results showed reduction in strength compared to the RM.
