Glass Fibre Reinforcement: Changing the Concrete Construction Industry

von Christian Witt

On November 6th 2012, Professional Engineers Ontario (PEO), Mississauga Chapter in joint efforts with Brampton Chapter, offered a Technical Seminar in the 244-seat Noel Ryan Auditorium at the Mississauga Central Library on Advancements in Glass Fibre Reinforcement.

The Central Library of the Mississauga Library System is one of the busiest libraries in Canada. The building officially opened on October 2, 1991 and was designed by Shore Tilbe Henschel Irwin Peters who also designed the Peel Board of Education headquarters and the police building in downtown Toronto.

The organizing committee first limited the registrations to one hundred attendees. However, due to the extreme high interest in the seminar topics, PEO allowed a larger number of registrations. At the day of the event, over 110 Engineers, especially from the Mississauga area, attended the seminar, resulting in a great success for the industry and for us. Angelo, Dritan and I had the opportunity to talk to many interested people leading to further technical lunch & learn seminars in the next weeks.

One of the guests came all the way from Germany. Selda Sorg, who recently joined the Team Emerging Markets at Schöck Bauteile in Baden-Baden, accompanied our team and learned some new and interesting things about ComBAR®. She was very tired at the end of the long day, but happy, she told me. Thank you Selda for your support during the event and for helping us setting up and cleaning up the venue.

Three renowned speakers presented different topics related to the newest material developments and test results from past and ongoing research programs in Ontario.

Dritan Topuzi, Product (Application) Engineer at Schöck Canada Inc. and PhD Candidate at University of Waterloo, introduced the newly developed ComBAR® Bent Bars as well as the latest test results from additional research programs at University of Waterloo.

Dr. Shamim Sheikh, Professor at University of Toronto, Department of Civil Engineering talked about the results from an extensive experimental program carried out at the University of Toronto on the behaviour of GFRP-reinforced concrete structures and the response of members under flexure, shear and axial load along with a study on bond between GFRP bars and concrete. In addition, he showed results from newest tests that clearly show that ComBAR® is a viable alternative in reinforced concrete piers and columns under Earthquake loading.

Dr. Khaled Sennah, Professor & Associate Chair for Undergraduate Program, Civil Engineering Department at Ryerson University presented “Sustainable bridge superstructure using GFRP technology” including the developed ComBAR® GFRP barrier wall and associated crash test as well as the use of GFRP bars with headed ends in accelerated bridge construction.

I would like to thank PEO and all attendees for the excellent organization, the incredible interest and the excellent questions during and at the end of the event. Schöck will definitely continue supporting this effort in the future.

Schöck Canada Inc. is focusing in training the engineering community in Canada and the USA in the design, use and applications of Glass Fibre Reinforcement. In certain situations, the material properties of the commonly used steel rebar do not meet the industry requirements. In these cases, ComBAR® can be installed. In Canada, the installation of ComBAR® is becoming increasingly common in situations where conventional steel reinforcement reaches its limits, due to its tendency to corrode in chemically aggressive environments and due to their magnetic and electrical conductivity. And also the USA is now considering the use of ComBAR® in their structures, some of which need immediate repair or replacement.

ComBAR® has a much higher tensile strength than steel and other available GFRP systems, is corrosion resistant, non-magnetic, easily machined and much lighter than steel rebar. This newest generation Glass Fibre Reinforcement is strong enough and extremely durable to be installed as permanent load-bearing reinforcement for 100 years and more.

New Generation 55 GPa ComBAR® Bent Bars: Now available in 12, 16 and 20 mm
New Generation 64 GPa ComBAR® Headed Bars: Now available in 12, 16, 20 and 25 mm
64 GPa ComBAR® Straight Bars with ribbed surface for greater bonding: Now available in 8, 12, 16, 20, 25and 32 mm

By the way, EBI was there too 🙂
