Abstract

In this study, concrete mixtures are prepared incorporating three different types of cement in 300 and 375 kg/m3 dosages and also 10-20 % F type fly ash (FA) replacement to cement, 36 different series are produced for tests after 28 and 180 days. Mechanical properties of these concrete types are determined. Besides, reinforced concrete specimens are also produced, accelerated corrosion test is conducted and after then adherence variations between concrete and reinforcement due to corrosion are determined by conducting adherence tests. As a result of tests, it is seen that there is no relation between bond strength and concrete quality, and bond strength of damaged specimens due to corrosion decrease in high ratios.

Özet

Bu çalısmada üç farklı çimento ile 300 ve 375 dozajlarında, katkısız ve % 10 ve 20 oranlarında F tipi uçucu kül (UK) katkılı beton karısımları hazırlanmıs, 28. ve 180. günler için toplam 36 farklı seri üretim yapılmıstır. Üretilen bu betonların mekanik özelikleri belirlenmis, ayrıca beton içine donatıların yerlestirildiği betonarme elemanlar üretilmis, bu numunelerde hızlandırılmıs korozyon deneyleri yapılmıs ve sonrasında aderans deneyleri yapılarak korozyon nedeniyle beton ile donatı arasındaki aderans değisimleri belirlenmistir. Deneyler sonucunda aderans dayanımının beton kalitesi ile iliskisinin olmadığı ve korozyon nedeniyle hasara uğrayan numunelerde aderans dayanımının çok yüksek oranlarda düstüğü görülmüstür.
