"The fact is you can use WWR anywhere you use regular rebar," says Dr. Maher Tadros, a professor at the University of Nebraska and principal of Tadros Associates of Omaha.
is so convinced of WWR's superiority in concrete reinforcement, that he
has undertaken a project in Omaha that has him building a concrete home unlike any other using only WWR as reinforcement.
Almost the entire home will be made up of WWR reinforced concrete panels from the floors to the walls to even the roof.
The project is being developed with the participation of four groups: The University of Nebraska
, Enterprise Precast of Omaha
, homebuilder TFF Inc of Omaha, and Dr. Tadros
"This project will really show off how WWR can be used in residential home construction.
I'm hoping that other builders will be able to use it as an example of how they can improve their building projects," says Professor Tadros
"The house will be a raised ranch style home, built with precast walls.
The envelope will be concrete, including the roof and the floor.
The basement and foundation will also be concrete.
All of the reinforcement will be WWR."
is hoping that this home project will dispel some of the misinformation about WWR and convince engineers and architects of its viability.
"Whenever I'm speaking to someone in my area about the benefits of WWR, I invite them to one of our local precast producers so they can see how WWR is used in bridge girders," says Professor Tadros
"Some of the girders can be two meters or 6 foot-7 inches tall, and WWR appears not only in a grid pattern in the flanges, but also as vertical shear reinforcement at even spacing in the stem.
WWR simply offers much more placement accuracy and structural efficiency than rebar.
As a significant bonus for the precast concrete producer, labor to fabricate these large girders has been cut by 30 to 40 percent.
It's always surprising to see the reactions because despite WWR being over 100 years old, people are shocked to find that WWR can be used for applications other than concrete driveways."
"When constructing a home that has concrete in either the walls, driveways or foundations, the most effective reinforcement is welded wire," says Dr. Tadros
