Bond of prestressing strand to concrete

Abstract

■ This article summarizes the research of various sources dating from the 1950s on prestressing strand bonding to concrete in support of the publication of “Recommended Practice to Assess and Control Strand/Concrete Bonding Properties of ASTM A416 Prestressing Strand.” The transfer of prestressing force from prestressed strand to concrete over a predictable length is essential for the reliable performance of prestressed concrete.
