Abstract

Abstract

A comparative experimental study showed that silane coupling agent solution can significantly increase the bond strength of new to old concrete repair interfacial layer. A primary modifying mechanism for explaining this phenomenon is proposed: it is possible for silane coupling agent to create many chemical bonds between cement paste surface and granite (old mortar) surface.
