Abstract

A series of fresh property tests and accelerated corrosion tests were used to develop grouts that combine favorable grouting properties with good corrosion protection. The grouts were then pumped into a clear duct with multiple drapes to observe their behavior under simulated field conditions. Two high performance grouts for post-tensioning applications are recommended from this testing. For horizontal applications, a low water-cement ratio grout with fly ash (Class C) is recommended. For vertical applications (such as tall bridge piers), a low water-cement ratio grout containing antibleed admixture is recommended.
