Debonding and fracture between deformed bars and early-age concrete
Abstract
The purpose of the present study is to obtain the bond characteristics of a deformed bar embedded in early-age concrete. The fundamental experiments, employing specimens with various covers of deformed bar, were conducted in order to investigate cracks around the deformed bar. The results indicated that in concrete within 1 day of age it is easy to generate internal cracks. The bond characteristics after an age of 2 days were properly evaluated by the equivalent bond stress. The increase of the slip could be induced by the damage of the concrete around the deformed bar.
