The use of industrial by-products, such as fly ash and recycled concrete, in building industry presents one of the ways to improve the effect of this branch of industry on environment. Experimental investigation shown in this paper had two directions. First direction was focused on investigation of the effect of using different quantities of cement and limestone powder as mineral filler in Self-Compacting Concrete – SCC. The second direction of investigation regarded the effect of the partial mass replacement of limestone filler with fly ash from thermal power plant ''Kostolac'' in two series, as well as with the ground recycled concrete in one series. The basic design requirement was to obtain the mixtures with good properties in fresh and hardened state. Relevant fresh SCC tests included slump flow, time t500, and density. Hardened concrete tests included change of density with time and compressive strength, up to the age of 28 days. All of the investigated series showed satisfacto...ry properties in fresh state and high values of compressive strength.
