- Steel rebar is ubiquitous it modern building. We put it in our footings, foundations, stem walls and slabs, and we also put it in our building envelopes. But how resilient is steel? And what happens when it rusts? Find out more in this video, and see why we think GFRP is the future.

This stuff is coming down in price really fast. I can get 7/16ths GFRP at the local Menards store for about 5 dollars each. That's less than regular steel rebar! The strength properties have been improving too as they seem to be using better polymers now for the resins. Its upwards of 7 times the tensile strength. Probably not anywhere near the compressive strength of steel rebar, but compression resistance is really the job the concrete itself should be doing anyway.
Good to know! I actually still have trouble finding it out here in Oklahoma. No one knows what it is, and I can't even get my big suppliers to get it. I got the last batch direct from the manufacturer. Happy to see the prices coming down and quality improving. Thank for comment.
Yea I’ve seen the same thing at Menards!
@@BuildingCulture Hi. Great video! Owens Corning is starting to create a distribution nationwide but not as quick as you would like I suppose. www.OwensCorning.com/rebar for more information.
There are two main types of products in this category. One is ASTM approved bar used for DOT applications like bridges and other like one that Menards sells for flatwork (slab on grade). One should really use ASTM product that is bit more expensive but still significantly less than galvanized or epoxy steel for masonary walls. Also ask for mill certs when dealing with this products. Quality control in GFRP production is important. There are good manufacturers and then others.

Interesting product, thank you for sharing
Welcome!
That’s great for straight runs, but how do you bend it?
Good question! You order corners pre-bent. I just order a bunch of 30" x 30" corner bars, and some L shapes for coming out of footing.
@@jimhabsfan Could you do it? Yes. I do not see why you cannot. Especially if you already have the steel.
Where we can see next video about how reinforce brick wall?
Yea...still need to make that :) Maybe on my next build!
Wonder if you can haul 4 times more per truck load too.
Yea when the limitation is weight, then definitely.
Sad how this or basalt rods don't get used more often.
Exactly.

How we bend the rods inside the site
i hope that's it easy to use :(
Field bends are not allowed as this material is made with thermoset resins. But suppliers like Owens Corning has a full line of factory made bends so it is easy to get stock 90 deg bends for example. More information is available at www.OwensCorning.com/Rebar. OC has two lines of product - one for DOT structural applications like bridges (available in #2 through #13 bar size) and other for flatwork and things like this video talks about available in #3 & #4.
Buy pre bent. Super easy to use!
Dr. Stone brought me here!
But only the manga Vol. 8 Chapter 70 title Paper Shield.

@@SuperCartoonist I have read the bible many times in my youth. It is not my favourite manga.

@@SuperCartoonist I guess that guy loves jesus too
not advisable for multi storey buildings, in case of fire those rebars melts and expect the building will collapse when the tensile reinforcement were gone.
I would expect most buildings that catch on fire will fail.
Also, our buildings are not relying on rebar to stand up. It's just there in case. So even if somehow the rebar melted in the middle of the wall, the wall will still function as a masonry wall, unlike a wood building that catches on fire.
@@BuildingCulture Yes, but steel begins to actually lose it's strength somewhere around 400 deg C - which only happens (remember the coating) with a really big fire which already results with massive structural failure of components. Epoxy used for composite rebars begins to lose it's properties since water boiling point. So at much lower temperature. It bonds with concrete to a lesser degree as well. And when there's shearing stress it snaps easier than steel rebar. So no... not a wonder material. It has pros and cons like everything. It does wonders in foundations though - no hazardous fire there, right?
Dude, you realize that rebar has only existed for 100 years, right? Brick buildings have stood for 1000s of years prior.
