To focus on the possibilities of using waste materials from different manufacturing activities in the preparation of innovative mortar and concrete. The marble dust from marble processing is a waste utilized. The use of this waste was proposed in different percentages both as an addition to and instead of cement, for the production of concrete mixtures. In the study, the use of marble dust collected during the shaping process of marble blocks has been investigated in the concrete mixtures as cementitious material. The study showed that marble wastes, which are in the dust form, could be used as cementitious material in concrete mixtures where they are available and the cost of construction is lower than ordinary concrete materials. The concrete is prepared containing 5, 10, 15 and 20 % waste of marble dust with cement compared to the total quantity of normal concrete. The prepared mixtures were then studied in terms of their properties both in fresh and in hardened state. In particular, tests were conducted and cured at different times to find compressive strength and tensile strength with and without partial replacement of marble dust in cement concrete and for mortar also determined for 14 and 28 days. Cost was analyzed for final result
