Structural Testing of Geopolymer Pipe/Culvert Mortar Lining
Track Title
Maintenance and Operations
Event Description/Abstract
Trenchless repair of both storm and sanitary sewer piping across the world has become one of the most effective techniques for updating the status of buried infrastructure while reducing the burden and disruption on the public. A new cost-effective and viable technology for the trenchless repair of large-diameter (>36 inch) pipes involves a sprayed geopolymer mortar to create a new structural pipe within an existing host structure. Recent testing on corrugated metal and reinforced concrete pipes has been undertaken to help engineers better specify and design a cementitious geopolymer structural lining. Results of completed testing at Queens University under the direction of Ian Moore, as well as testing performed under the direction of Erez Allouche at the Trenchless Technology Center at Louisiana Tech University, will be presented and discussed.
