Özet

This study examines the influence of the physico-mechanical properties of the intact rock of aggregate materials on the strength performance of a concrete. For this aim, nine different aggregate types were produced from nine different intact rocks, and they were used in the production of nine different concretes. The physical and mechanical properties of the corresponding rocks were varied between 7.8 and 123.3 MPa, 13.30 and 26.40 kN/m3, 2.29 and 34.43%, and 1.30 and 4.34 km/s, for compressive strength (CSr), unit weight (UWr), porosity (nr), and ultrasonic pulse velocity (UPVr), respectively. During the making of the concretes, water–binder ratios were kept between 0.28 and 0.55 based on the slump and workability. According to 28-day compressive strengths, strong correlations were obtained from the physico-mechanical properties of the corresponding aggregate rocks and the compressive strength of the concretes (CSc). While the increasing the Young’s modulus (Er), CSr, UWr and UPVr of corresponding aggregate rocks increased the strength of concretes, the increase in the nr of corresponding aggregate rocks decreased the strength of concrete. The results obtained from this study indicated that knowing any physical or mechanical property of rock used for producing aggregate could be used to estimate the compressive strength of concrete.
