dc.description.abstractIn this study, the process of withdrawing the concrete mixture water by vacuum was applied to a field concrete at different times while it was fresh. By applying vacuum to fresh concrete, some of the mixing water in the concrete and also the trapped air was removed in a controlled manner. In the concrete blocks produced to be 15 cm thick, the names A or reference, B and C were respectively given to concrete block without vacuum, 17 minutes vacuum applied concrete block, 35 minutes vacuum applied concrete block. Core samples of 75mm diameter and 150mm length were taken from the vacuum concrete blocks, which were exposed to outdoor conditions for 66 months in Ankara. In addition, three samples, 75 mm in diameter and 50 mm in length, were prepared from each of the cores taken, as lower, middle and upper. Thus, the compressive strength, abrasion resistance and capillary water absorption effect of vacuuming time at different depths of concrete were investigated. As a result of the study, it was observed that the compressive strength and abrasion resistance of the reference concrete increased, the amount of capillary water absorption decreased and the capillary coefficient decreased as it moved away from the upper surface of the reference concrete. It was also observed that as the vacuum moved away from the vacuum applied surface, the compressive strength and abrasion resistance of the concrete decrease, the amount of capillary water absorption increases and the capillary coefficient increases.
