Abstract: “The purpose of this study is to compare Self Compacting Concrete (SCC) and Conventional Concrete (CC) which are used in beams with dense reinforcement, in terms of their apparent volume of permeable voids (AVPV). During the comparison of SCC and CC, the effects of two different factors were also investigated: strength class of concrete and curing condition. In the study, both SCC and CC were produced in three different strength classes (C25, C50 and C70) and the other parameter (i.e. curing condition) was determined as two levels: moisture and air curing. Beam dimensions were determined to be 200x250x3000 mm. The AVPV measurements were performed on core samples taken from the beams. Core samples of ø8x5 cm were taken from the beginning (0-100 cm), middle (100-200 cm) and end (200-300 cm) region of the beams according to the casting direction of SCC. In the study, AVPV experiments were performed according to Turkish Standard 3624. It was observed that, for both SCC and CC, AVPV values o”
