Özet

Roller-compacted concrete (RCC) is highly preferred today due to its quick applicability, economic, and sustainable nature. Research in the literature shows that while there is extensive work on RCC, there are no studies related to void determination using petrographic analysis. Within the scope of this study, petrographic analyses were conducted on samples produced using different compaction methods suh as vibrating table, vibrating hammer, superpave gyratory compactor and modified proctor with a high-resolution petrographic microscope. The effects of varying water content and cement dosage on the void ratio of the concrete mixtures were examined. As a result of the study, the best compaction method was determined to be the superpave gyratory compactor method, with the lowest void ratio obtained from samples produced with 400 cement dosage containing 6% water.
