Abstract

In this study, the performance of some non-destructive tests for the determination of compressive strength of concrete was investigated. Windsor probe penetration test, Schmidt hammer test and Ultrasonic test which are non-destructive test methods were carried out on hardened concrete. Besides of non-destructive tests, compressive strength of concrete was determined directly by using core samples taken by coring. Compressive strength of concrete specimens determined by destructive testing was compared by the values determined by non-destructive tests. As a result, Windsor Probe Penetration Test determined the compressive strength values with 2.5 % accuracy according to destructive core sample testing. This accuracy is about 5.4 % at the Schmidt hammer test and 3.5 % at the combined method.

Özet

Bu çalışmada, bazı tahribatsız test metotlarının vakum uygulanmış betonların basınç dayanımlarının belirlenmesindeki performansları incelenmiştir. Bunun için aynı karışımdaki betona farklı sürelerde vakum uygulanarak 3 farklı özellikte beton hazırlanmış, bu betonlarda tahribatsız test metotlarından windsor probe penetrasyon testi, beton test çekici ile yüzey sertliği ve ultrases geçiş hızı deneyleri yapılmıştır. Ayrıca, beton bloklardan alınan karot örneklerin tek eksenli basınç dayanım değerleri belirlenmiştir. Karot örneklerin tek eksenli basınç dayanım değerleri ile tahribatsız test metotlarıyla belirlenen basınç dayanım değerleri karşılaştırılmış, sonuç olarak karot örneklerden elde edilen basınç dayanımlarını, windsor probe penetrasyon testi ortalama % 2.5, schmidt çekici % 5.4, bileşik metot ise % 3.5 yaklaşıklıkla belirlemiştir.
