Bridges and barrier walls are often constructed of reinforced concrete, a material where the low tensile strength of concrete is compensated by the high tensile strength of steel. Steel rebar is commonly used within the concrete, however, certain properties of steel, such as electrical conductivity, magnetism, thermal conductivity, and most importantly, low resistance to corrosion, may negatively affect the performance of a reinforced concrete bridge.
Depending on the application and conditions of the structure these properties of steel can affect the performance of bridges. Corrosion control is crucial in reinforced concrete bridges, especially when exposed to de-icing salts. Corrosion of steel reinforcement in bridges causes increased maintenance cost, and if not properly maintained, it affects aesthetics and can lead to structural collapse.
These corroded bridges are found practically everywhere. The Gardiner Expressway in Toronto is a prime example of steel rebar corrosion, and was best described in an article by Dr. Paul Gauvreau on The Globe and Mail, “Toronto’s crumbling Gardiner: Bring on the engineering innovation.”
“…Gardiner was built with materials and structural details that make it prone to deterioration and difficult to maintain…”
Construction began in August of 2011 on Windsor Essex Parkway in Ontario and is expected to complete in late 2014. Schӧck ComBAR® GFRP is included within bridge barriers in $1.4 billion highway infrastructure project in the municipalities of Windsor, LaSalle, and Tecumseh, in Ontario, Canada. The parkway is now called Rt. Hon. Herb Gray Parkway, following the renaming in 2012.
The goal of the project is to improve traffic flow at Canada’s premier trade gateway from Canada to the US, carrying 28% of Canada’s trade with the US. This route goes through Windsor and links Detroit to Ontario’s Highway 401. The parkway prides itself on the community enhancements and environmental features of the project. … read more
Spring and summer have been some very busy months for us and we would like to highlight a few projects which incorporated ComBAR® glass fibre reinforced polymer rebar.
The most scenic construction site is just behind the Niagara Falls.
Last month, Schӧck in the UK was contacted by an American engineering firm wanting to find out some information on a nonmetallic concrete reinforcement product.
The UK office immediately forwarded this inquiry to our offices in Baden-Baden Germany. Germany which in turn notified the offices in Canada and the contact information was provided to myself here in the United States. … read more
The business has been extremely rewarding this past year. The sales of ComBAR® climbed drastically and achieved 3 times the sales volume of 2011. We have also noticed that GFRP is now a common building material and is being specified in a great number of bridge and tunnel structures, especially in Ontario. But also the United States has been an interesting market in 2012. Besides, we have seen a great interest in the future use of GFRP in New Brunswick, Manitoba and British Columbia.
In 2012, we also had an amazing and successful introduction of our Thermal Break Element, the Schöck Isokorb®. Isokorb® has being installed in over 10 different buildings across Canada! We are now starting to convince architects, engineers and primarily developers and owners about the unique advantages of the Isokorb® to minimize energy consumption, improve the quality of living space and subsequently protect the environment in which we all live and in which our children and their children will live in the future.
A year has gone by and we would like to review the great development with you: Important projects we completed and our efforts to expand east and west in Canada as well as in the USA
We have had a good year with ComBAR®. Some jobs we have completed this year are: Queens University Reactors, WEP Bridge 15, Barb Road Bridge Rehab, York/Durham Sewer Caissons, Bonnechere Bridge and Canal Bridge. North Channel Bridge has been released and completion is scheduled for 2013. We are looking forward to 2013. The buzz is that the MTO is preparing packages for a number of bridges in a single release. We also heard that epoxy coated rebar will no longer be used by the ministry, which will hopefully open up a new market for GFRP in the next few years.
Annual Ontario Concrete Awards Banquet honors the most creative and visionary projects that have made concrete their construction material of choice. This year it was held on the 28th of November at the Metro Toronto Convention Center, in Toronto.
Awards are given for the following categories: Architectural, Structural, Materials & Constructability, and Sustainability. ComBAR® GFRP, as an innovative material, provided points to the Whitemans Creek Bridge project, which received the Structural Design Innovation Award, in the Structural Category.
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.
Gathering in Toronto were the intellectual elite, as it pertains to the application of concrete in North America. To say that I was out of my element is the understatement of the decade. For the layman such as myself it was like watching paint dry in super slow motion. The conversations so technical, the subjects dissected down to the most minuscule detail. The questions of where to change a period at the end of a statement, or to move details from the opening of a specification to the middle were all lost on this humble Sales Associate. … read more
Last week I had the chance to attend two important conferences in Toronto and Mississauga.
The first one was the ACI Fall 2012 Convention, at Sheraton Centre in Toronto. ACI (The American Concrete Institute) is one of the world’s leading authorities in concrete technology. It conducts two conventions a year and this Fall the event was held in Toronto. Domenico and I attended the Convention for two days, the 22nd and 23rd of October, where we introduced Schöck and our products to several potential clients. An important event was the ACI 440 Committee meeting. ACI 440 is an ACI Committee focused on fiber-reinforced polymer reinforcement. During this meeting we heard good news about the Committee’s plans with regard to further developments of codes and guidelines related to the FRP reinforcement in concrete structures. At the end of the meeting we talked to Mr. Busel, a director at ACMA (American Composites Manufacturers Association), and Dr. Shield, the ACI 440 Committee Chair. We have an application in process for becoming a voting member of this Committee, in order to have our say as a local FRP supplier on the future development of codes published by this prestigious institute. … read more
The Schöck Isokorb® team is a unique group of professionals, originating from different countries and cultures. We work together to bring the best services and products. But on the other hand we are a group of real and interesting people, who have their own interests, hobbies and diverse life experiences.
Each of us has prepared a short bio, which filled with personality type and quite interesting to read!
North Channel Bridge and Canal Bridge are two projects in eastern Ontario incorporating ComBAR® GFRP reinforcement. These bridges are both part of the Three Nations Bridge Crossing project (also called the Seaway International Bridge) in Cornwall, Ontario. This international border crossing was named in honour of the Mohawks of Akwesasne who inhabit the region. … read more
Schöck began blogging in January of 2009 with the introduction of the Schöck Company blog in Germany. Now, here we are, 3 years later, with the introduction to our Schöck blog in North America.
We are excited to begin sharing some insight to the inner-workings of Schöck and our dynamic teams in Canada and the USA.
