Abstract
In this paper a comprehensive experimental investigation on the residual bond strength between the early aged fly ash concrete and steel ribbed bar after exposed to high temperature has been presented. The research focused on the influences of different temperatures, curing ages, cooling methods and standing times of the specimens after high temperature. A total of 177 pull-out tests were conducted under different conditions. The research indicates that the curing ages of fly ash concrete, exposed temperatures, cooling methods and the standing time of the specimens after cooling have considerable influences on the residual bond strength of fly ash concrete. The research generated a set of reliable and valuable test data for the researchers and practical structural engineers in the field of structural fire engineering.
