Abstract (2. Language): 
In this study, Bond grindability test, Uniaxial compression, Indirect Uniaxial Tensile, Los Angeles Abrasion (K500) and (K100), Point Load Index, Sound Velocity, Shore Hardness and Schmidt Hammer tests were performed on four different limestone and two different chromites samples. The relations between Bond Work index and the other test results were investigated and the best correlation was found between Bond Work index - Sound Velocity with r = 0,93 and the other acceptable correlations were between Shore Hardness and Bond Work index with r = 0,93, Point Load Index - Bond Work index with r = 0,88 and Uniaxial Compressive Strength - Bond Work index with r = 0,77. According to this results Sound Velocity, Shore Hardness, Point Load Index and Uniaxial Compressive Strength tests could be used to simulate the Bond Work index rather practically, speedily and economically than the Standard Bond Test.

Abstract (Original Language): 
Bu çalışmada, dört farklı kalker ve iki farklı kromit olmak üzere altı farklı kaya için Bond Öğütme deneyi, Tek eksenli basma, Dolayl Çekme, Los Angeles aşınma, Nokta yük, Ultrasonik ses geçirgenliği, Schore sertlik ve Schmidt sertlik deneyleri yapılmıştır. Bond İş İndeksi ile diğer deney sonuçları arasındaki ilişkiler araştırılmış ve en yüksek korelasyonu r = 0,93 ile Ultrasonik Ses geçirgenliği - İş indeksi, r = 0,93 ile Schore Sertliği - İş İndeksi ve r = 0,88 ile Nokta Yük İndeksi - İş İndeksi, r = 0,77 ile Tek Eksenli Bas nç Dayan> > - İş İndeksi arasındaki ilişkiler vermiştir. Buna göre Ultrasonik ses geçirgenliği, Shore sertliği, Nokta Yük İndeksi ve Tek eksenli basınç dayanımı değerlerinden hareketle Bond İş İndeksinin daha pratik, hızlı ve daha ekonomik bir şekilde belirlenebileceği görülmüştür.
