Abstract:Stressed steel cables greatly increase the strength and capability of concrete structural components, providing tensile strength that concrete alone does not possess. The cables – called tendons – run through sealed tubes in the concrete which are filled with grout.
Florida International University researchers examined the contribution of grout to corrosion of post-tensioned steel in concrete construction. A better understanding of the effects of grout composition and behavior on steel posttensioning tendons can lead to better product specifications and installation procedures, reducing corrosion, maintenance, and replacement costs for structures that use this technology.
