Concrete, which is frequently used in the production process of buildings; It is made by mixing cement, water, aggregate and additives in appropriate amounts. It is important that the physical, chemical, mineralogical and especially mechanical properties of the concrete are at the desired level in terms of strength and durability of the built structures. In this direction, the selection of aggregates, which are an important part of the concrete mix, is one of the important factors affecting the concrete properties. The use of limestone and dolomitic rocks, which are rocks of sedimentary origin, in the selection of aggregates, strengthens the adhesion of aggregates with cement and improves the properties of the concrete mixture. In this study, it was aimed to identify and classify the rocks in the Western Anatolian region of Turkey and to investigate the suitability of their use as aggregates in concrete. In this context, when the physical, chemical and mineralogical properties of the rock samples taken from the field area were examined, it was understood that the rock samples were limestone and dolomitic limestone samples. In order to compare the performance of concrete mixtures prepared using limestone and dolomitic limestone aggregates, a total of 18 concrete samples were prepared, including limestone crushed aggregate, dolomitic limestone, and limestone and dolomitic limestone aggregates used together. At the end of the 7 and 28 days curing period, the concrete compressive strengths of the prepared samples with the intention of being used as concrete in building structures were tested and compared.
