Abstract :Aggregates have a large volume in concrete, therefore they directly affect the properties of concrete. Aggregate, which is expected to give desirable strength in concrete, should be examined especially in terms of its physical properties and grain size. In this respect, aggregate to be used in concrete must not be easily broken, non-abrasion quickly, and must be strong and hard structure. While low strength is obtained in concrete produced with porous lightweight aggregates, high strength is observed in concrete produced with high-density aggregates. In addition, aggregates have an effect on concrete properties such as concrete workability and permeability. One of the aggregates commonly used in concrete production is limestone aggregate. In this study, the effects of limestone aggregates with different properties on compressive strength and splitting tensile strength were investigated experimentally. In this context, cubic specimens of 150×150×150 mm dimensions were prepared for different water/cement ratios, different cement contents, and different aggregate properties. With these specimens, after the cure period of 28 days, the relevant strength tests were performed. The strength values of these concrete specimens were compared and the results were discussed. As a result; it has been determined that the concrete strengths obtained by considering the relevant standards are compatible with the literature. Thus, in this study, it has been determined that aggregates tested for use in concrete have positive effects on concrete strength.
