Deneysel çalışmada, C30/37 sınıfı silindirle sıkıştırılmış beton (SSB) tasarımı yapılmıştır. Karışımda, CEM I 42,5 R portland çimentosu, dört farklı boyutta agrega ve şebeke suyu kullanılmıştır. Su/çimento oranları 0,32, 0,35, 0,38 ve 0,41 olarak belirlenmiştir. Farklı su/çimento ile yapılan karışımlarda su miktarı sabit tutulmuş, çimento ve agrega miktarlarında değişiklik yapılmıştır. 7 ve 28 günlük basınç dayanımlarının tespiti için 15 cm çapında ve 30 cm yüksekliğinde silindir, 28 günlük eğilme dayanımları için 15 cm x 15 cm x 75 cm boyutlarında prizmatik kiriş, basınç altında su işleme derinliği ve aşınma için ise 15 cm x 15 cm x 15 cm küp SSB örnekleri üretilmiştir. Elde edilen veriler sonucunda, silindirle sıkıştırılmış betonlarda su/çimento oranının, basınç dayanımı, eğilme dayanımı, basınç altında su işleme derinliği ve aşınma gibi betonun özelliklerine etkileri belirlenmiştir.

Anahtar Kelimeler

The Effects of Water/Cement Ratio on Properties of Roller Compacted Concretes

Öz

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.
