Abstract:

In this study, the usability of Triassic aged limestones, which are widely distributed in Kocaeli - Gebze Tavşanlı region, as concrete aggregate was investigated. In addition to the geological and petrographic properties of the rock samples taken from the outcrop of the crushed stone quarry, the chemical, physical and mechanical properties of the aggregate samples obtained by subjecting the rock samples to size reduction and classification in crushing and screening plants were investigated by performing standard aggregate tests. In addition, in order to investigate the effect of aggregate properties on concrete, concrete experiments were carried out and their use as aggregate in normal strength concrete was investigated. In addition to the petrographic properties of the examined limestone aggregates, it is appropriate to use them as concrete aggregate because the aggregate properties and concrete test results are within the acceptable limits specified in the standards.
