1990. Grouting of tendons in prestressed concrete. (PDF)

In 1975 and 1978, the FIP Commission on Practical Construction published Guides to Good Practice for grouting of tendons.¹ ² At a later stage, it was decided to combine both reports into a single document and, at the same time, to incorporate the latest developments in grout materials and grouting techniques. A Working Group was therefore formed, with Mr. J. Groenveld as Chairman.

The importance of proper tendon grouting for achieving durable corrosion protection and effective bonding between prestressing steel and concrete has long been recognized. However, the execution of seemingly straightforward procedures is sometimes treated too lightly. In recent years, many prestressed concrete structures have been inspected, and it has been found, often surprisingly, that tendons were not properly grouted or, in some cases, not grouted at all. In this respect, this Guide to Good Practice is being published at an appropriate time. It emphasizes the essential aspects of proper grouting techniques.

I am convinced that the industry will accept this document as a valuable guide. I would like to thank the Chairman and the members of the Working Group for their very important work.
