Abstract: “In this study, the results of the mechanical and physical tests on the concrete that has batch and continuous granulometrics aggregate have been analyzed. For this purpose, 300-400 doze concrete samples have been produced from streams and crushed stone aggregate. The ratio of water/cement was taken as 0.50 in all of these mixtures. Maximum grain diameter (dmax) of the aggregate was chosen as 32 mm. To create a step gradation, the aggregates that has equivalent (0-4), (4-8), (8-16) and (16-32) mm sieve eye openings were subtracted from the aggregate stack, respectively. Crushed stone aggregate with continuous granulometrics and streams aggregate with batch granulometrics except (8-16) mm has shown high mechanical performance.”
