Özet: In the experimental study, roller compacted concrete (RCC) with concrete class of C 30/37 was designed. CEM I 42.5 R Portland cement, four different sizes of aggregate and tap water were used in the mixtures. Water/cement ratios were determined as 0.32, 0.35, 0.38 and 0.41. The water amount was kept constant where the cement and aggregate amounts were changed in concretes having different water/cement ratios. Cylindrical specimens with a diameter of 15 cm and a height of 30 cm were produced for the determination of the compressive strengths at the ages of 7 and 28 days. 15 cm × 15 cm × 75 cm sized prismatic beams were produced to determine the flexural strengths at the age of 28 days while 15 cm × 15 cm × 15 cm cubic RCC specimens were produced to determine the depth of water penetration under pressure and wear resistance. According to the results of the data obtained, the effects of water/cement ratio on properties of concrete were determined.
