According to various code provisions including ACI 318-08, the bond strength and the correspondingdevelopment length are related to the square root of the concrete compressive strength. This impliesthat the relationship between bond strength and the square root of compressive strength is linear. Inthis study the normalized bond strength was introduced in this study. The normalized bond strengthwas defined as the calculated experimental bond strength divided by 'c F . The normalized bondstrength nz can be expressed as given in equation (2):
