Rehabilitation of civil works hydraulic concrete structures such as navigation locks or stilling basins commonly involves the removal of defective concrete and replacement with new concrete. Steel reinforcing anchors are normally embedded into the base concrete to assist in the attachment of the base concrete to the new concrete. With respect to bonding the steel anchors into the base concrete, this investigation was conducted to evaluate the effectiveness of cementitious, vinylester and epoxy grouts in bonding embedment of these anchors. Tensile pullout and longterm creep strain tests were accomplished in this study in correlation with parameters for dry and wet environments and for bond maturity ages of 1,3,7,28 days and 1 year.
