SHOULD I USE REBAR OR WIRE IN CONCRETE ??? (MIKE HADUCK)

[@qoolqoin7869]

Hey Mike, long time viewer here. Sorry for the long post, but here are a few points of interest everyone might like. Fiberglass rebar has actually been around about a hundred years. I'll get back to that in a sec, but first some quick history (just the high points)... the French "invented" or popularized the use of steel rebar in the mid 1800's. In the days of few building codes, it was slow to be adopted in the US. Then, in the early 1900's, a bell tower near San Francisco was built using steel rebar. Many engineers of the day made fun of it, and said using steel rebar was overkill, and a big waste of money. But when that bell tower was still standing after the great San Francisco Earthquake of 1906, a trend set off in America for using rebar in concrete. This trend was "reinforced" a few years later in 1910 when 10 construction workers were killed by a masonry wall collapse. The blame was given to "not enough rebar used" when in fact the failure was caused by the premature removal of some critical shoring. Big stories like these hitting the newspapers (going viral) back in the day - that's how the stupidity of steel rebar really took over in this country. Engineers bought into the hype without really knowing the facts. Any Chemist, Geologist, or Geophysicist could have told them that concrete is a sponge and steel rebar is NOT a good thing to mix with it. Anyway, both fiberglass and basalt rebar have been around longer than most people realize. Up until a few years ago, it was WAY more expensive than steel rebar, but that's not really the case any more. It was traditionally only used in marine environments, so even though it was costly to buy up front, the savings on later fixes made it actually cheaper in the long run. Fun Fact: Walt Disney used a ton of it the construction of his parks. Years later (1998) when they went to demolish the old "Submarine Voyage" ride in the Anaheim park, they had a terrible time tearing out the old concrete because the fiberglass rebar concrete was still extremely strong. The concrete was too thick in places so cutting wasn't an easy option, and the concrete was held together with such monolithic strength that they were all scratching their heads at first. Eventually, they had to hire extra-heavy equipment to remove it and it took a lot longer to do so. And after 40 years of being in place, it was noted that the rebar was "still like brand new." I wish we could say the same for all our bridges in the US. By the way, the Mckinleyville Bridge over Buffalo Creek in WV built in 1996 is the first vehicular bridge in the U.S. to be done with fiberglass rebar. Well, it's a start... one down, and 617,000 or so to go (there are roughly that many bridges in the US). FYI, if anyone is going to get into non-steel rebar, please don't buy the junk that comes from various places overseas. It's no good. There's a place in Texas that makes it called Kodiak, and I think they're one of the few who actually manufacturer it here in the US. They may be the only one. A lot of companies will tell you they make it here, but they actually just sell the imported junk. These companies will "assemble" it here in the US (eg. they'll make the corner bends here) but then they dishonestly say it's 100% "made here." Don't be fooled. Now, I don't know the guys in TX, so I'm not trying to plug them, it's just a fact that they actually make it here in the US. FYI, the psi of fiberglass rebar is 75,000 to 150,000 depending on which size you get. That is CRAZY strong! You would have to pay big bucks for grade 40, 60 or 75 in steel rebar to get those kind of psi strength ratings, and you'd still have the rust problem. So if you need strength - fiberglass or basalt rebar is a lot cheaper than steel compared to the same psi for steel. And you won't EVER have to redo your project due to rusting, cracking, spalling, etc of the concrete... heck, even your great, great grandkids won't have to redo it if you use fiberglass rebar from the get-go. One last thing... the worlds strongest concrete according to rigorous scientific verification is a section of breakwater/seawall in the Bay of Pozzuoli, near Naples, Italy. It's the strongest and it contains no rebar. Mainly because it was built there in 37AD by the Romans. This concrete is actually stronger than the day they installed it nearly 2,000 years ago. It actually gets a little stronger ever year (thanks to a process called Al-tobermorite crystallization). Thanks for all your great vids over the years Mike. Pin this to the top if you want everyone else to see it.

Thanks Gibson, I agree, Mike

[@smelchionda]

I love your videos! Your experience is invaluable and I love how you travel the world and look at stone and masonry work through out history to gain perspective and learn from the past! Regarding the use of rebar in concrete. One thing that I think could have been better communicated is that rebar inside of concrete isn't just to hold it together when it cracks, it is also there to give concrete structural rigidity. Concrete without rebar wouldn't be able to span the same distances or carry the same loads. The two work together; rebar provides the rigidity and concrete provides the compressional strength. You could build with out rebar but you would have to use much more material and every span would have to be an arch.

[@MikeHaduck]

Thanks Sean, mike

[@Blue1Sapphire]

On longer spans, tensioned rebar is better as untensioned rebar flexes before concrete does, causing concrete to crack.

[@daviddixon2209]

Putting steel in concrete makes it a "temporary" construct. My house is 25 years old and, the lintel above my garage door is expanding and cracking the mortar joints above it. The first house I ever remodeled was a brick two flat in Chicago. All the windows were arched as you described and, the brick was in perfect condition.

I heard the PH of the concrete would preserve the rebar unless it gets constant water infiltration. I have been coating my concrete work with heavy duty Concrete paint that comes in 5 gallon buckets with some kind of a grit like material in it shortly after I remove the forms...Every now and then I’ll see a 5 gallon bucket of it at the big box store in the oops / Clarance MisTint area and pick it up for $10 or $20 versus $120 regular price. I also try to use a zinc rich primer and some kind of paint over anything that’s getting buried in the concrete pour. I always feel sort of OCD when I’m doing this stuff but I hope it last a little longer.

[@MikeHaduck]

Hi CY, I always say, anything that works, thanks Mike

[@FishFind3000]

My neighbor just redid his driveway and the city would not allow him to use rebar. I said that’s stupid it’s gonna separate. Later on he mentioned your required to use fiber. That coupled with what you said and us being in the Chicago area makes sense. A specific psi plus fiber is better for our environment as long as the base is good and there’s no shifting.

[@MikeHaduck]

That makes sense, I heard it because of recycling, thanks Mike

[@lizzapaolia959]

Outstanding video. We shared this information with a friend who lives in Mendocino County, CA. They have a lot of rain and moisture. He's going to purchase non metallic rebar for his pato and walkway. He's also introduced in the fiber mesh for concrete strength...... We are very grateful too you for sharing your knowledge. God bless 🙏

Thanks lizza, God bless. MIKE

[@74stevedc]

I agree with you on the rebar and wire, we post a video pouring a floor no wire you get the comments. We post a video of no rebar in a wall same thing. People think if you put rebar in a wall it won't crack it's just not true. If you don't put wire mesh in the floor same thing it will crack. Concrete will crack because it shrinks during hydration a 100' wall shrinks 3/8 so it will crack probably 3 times in that distance could be more. The rebar is just a threaded rod holding the crack on both sides together until water gets in and moisture and oxygen cause rust there is the cycle. Same with the floors.

I'm currently doing a small extension on the garage, and i've dug into hard clay. It's summer, and the ground is rock hard, especially clay. Although in my eyes I've over engineered this small project, I'm still using rebar. I've watched your vids and decided to use it, but making sure its 4'' in from any tench side wall.

Rebar helps the concrete resist Tension and bending or when concrete is weak (not compression). They pretension the wires running through the concrete beams pour the concrete and release the wire Making a pre-stressed concrete beam When you stand on top of a beam, one side is in tension, and one side is in compression.. Rebar helps this loading and so does prestressed wires.

In Australia now we have the book reading brains trust interfering with repairs to old buildings now. My mate had to build a three foot doorway in a stone masonry home . They required that he use a t beam with a 1ft upstand over it. End bearing of 600mm or 2ft end bearing. The original lintels in the 3ft openings was 4x2 Douglas Fir with 6 inch end bearing. I have to get engineers calculations on openings in a stone home im renovating. They want the roof width so they can calculate roof load. There is 4 ft of wall above the opening to the roof. As you know Mike masonry work over an opening forms a natural arch, So a lintel only holds the masonry under that arch in place. That's why they only use a 4x2 Douglas Fir over a 3 ft opening. Ive put new lintels over doorways where the termites have destroyed the timber lintel. The only loose masonry is in the natural arch above the lintel. Unfortunately the powers that be are using criteria that only applies to the temporary garbage they build now to apply to the older permanent structures. Common sense is dead Mike.

[@Don.Challenger]

When they are doing demolition/deconstruction they should study, observe and document (in video to economize the time cost of that study) and use the results to calibrate their engineering methods. Much of Mike's work is removing the previous job before he can prepare and do his own replacement/renewal/enhancement and by it much knowledge is found/gained in that necessary removal.

Mike, a ticking time bomb is Mexico City . A city built on loose alluvium soil with no reinforcing steel. If an earthquake strikes Mexico City the structures without rebar will be death traps. Rebar saves lives in earthquake active zones. California you cannot lift a trowel without an inspector verifying rebar placement. Overhead block work over doors have to have rebar and 2000 psi grout. But you are right about getting carried away with rebar in small projects. The bridge support again you showed if an earthquake occurs will keep the bridge from collapse. Concrete looks awful ; however, not all places are geologically stable English Castles.

Hi Michel, I did a video called " industrial concrete work" Mike haduck, sewer plant, plus all the concrete work I did in union work, and I never seen concrete that did not crack or leak, thanks Mike

Doesnt anyone make stainless steel wall ties for brick or stone walls?

[@MikeHaduck]

Hi Beach, the new schoolers who design buildings design for a period of 35 years by default, conwy castle was built 20 years before Columbus discovered America, and it's still there, they used no rebar, stainless steel, etc etc, you can see what I mean, thanks Mike

[@beachboardfan9544]

@@MikeHaduck Yea but is that really a good comparison? How thick are those walls and probably even more important, how much would it cost to build today?

[@MikeHaduck]

Hi, I guess my answer would be, How long do you expect it to last? And then go from there, thanks Mike

[@sammyd7857]

The whole rusting of rebar problem is vastly exacerbated by using a poor quality concrete mix. Also making sure that any steel is completely encased will prevent rust. The main thing though is quality of concrete, so the fact that this guy didn't mention that means he doesnt know much.

Hi Sammy, our family been in the concrete business over 75 years, I just tell what my experience showed me, thanks Mike

[@sammyd7857]

@@MikeHaduck ok but it should be mentioned the fact that higher psi concrete will inhibit rust. There have been tests done on adding nitrite also.

Why not Bamboo👌

Hi Moss I see it done in Asia, Mike

[@robertduffy5805]

So would you say the fiber or plastic/fiberglass rebar would be better and maybe give a few years extra before the concrete?

[@MikeHaduck]

Hi Robert, I cant say, I dont think it hurts but I dont think enough time hasn't gone by for a final answer, thanks mike

How was the Atlantic Wall (WW2) and Hitler's bunker built, that the following governments tried to blow up and demolish, but it's so tough that it won't break apart? It was reinforced concrete and the rebar isn't doing its job.

[@MikeHaduck]

Hi. I got videos on the pyramids of Egypt,, peru, Mexico, the castles of Europe, cathedrals. They never used rebar and they are still there, everthing built is for their purposes, thanks mike

[@eveliinatistelgren172]

@@MikeHaduck thanks I'll have a look! And I meant the rebar still didn't do its job (of expanding and breaking) those WW2 fortifications like casemates. And it's been nearly 100 years.

[@sammyd7857]

High strength concrete will stop rust for longer than 35 years. Why do people think concrete tanks last so long(longer than 35 years)

[@MikeHaduck]

Hi Sammy, I worked with concrete tanks and they actually made concrete barges and sailboats, but no insurance company will insure them, they rot away, thanks Mike

Mike, my Grandfather was a bricklayer in Cleveland, Ohio. He had such pride in his work and as a kid he would show me different styles of bricklaying. He also built a lot of stone fireplaces and floors. He and my grandmother were my favorite people ever!!! Your accent and teaching style remind me so much of him. He would have loved your KZbin channel, I am sure.

Back in the late 70s I had a contract on military bases building walls for substations. The plans called for rebar every 12” in the walls which were underground. We rodbusted, built forms and did concrete to save money. If we spaced one 13” the inspectors would act like they caught John Dillinger. Pretty sure tax payers have have paid to replace those......with the same specs. Nice video, very helpful....use common sense.
