Love your vids BTW. Learnin every day! .... Here in the Beautiful village of Bellows Falls {aka Fellows B***s] Vermont, we have a concrete stairway that goes from the village square to an upper tier. It is older than me and I am 66 and it surprisingly has had very little repair work done even though it gets salted HEAVILY in the winter. But in other parts of the village I have seen new concrete jobs and repairs that deteriorate practically before your eyes. And they tell me it is because of the salt!!! Wassup with this???

Steel (rebar) is cheap strength, a few more bars won't cost that much. If you are unsure of necessity to add water at the job- batch(buy) higher strength psi. These are the cheapest ways I've found to turn variables in your favor on tough days. Enjoy the videos thanks for sharing

Concrete is very cool. Here in Japan we have earthquakes, our concrete cracks. The concrete that our 7 floor building is made from actually heals itself if cracked. We had a crack in the floor of the first floor entrance after a big earthquake, this floor is the ceiling of my B1 workshop, well the first time it rained I had a small leak, but since the water found it's way into the crack once, it has never leaked again. There is this crystal in the concrete that when exposed to water, the crystal grows and fills the crack. Some very cool stuff. Cheers!

As a painting contractor, Im used to other contractors second guessing and trash talking each others work. Its easy to do and Im guilty of it myself. Anyone can look for problems, the real trick is to find out what a guy did right, and use that for myself. And most of all, if the customer is happy, dont ruin that for them by nitpicking the last tradesman, unless there is a real safety issue, or your gonna fix it yourself.

@MelikeKTMs 4 года назад

Nathan Weese Brother, Thats an excellent way of putting it.

I always expected my painting contractors to make my work look good or I would never use them us carpenters need our painters to make us look good we all win but I always deliver an excellent product and like you said I don't like to nit pick someone else work we all can do that.

Just wanted to thank you for the appreciation you show towards concrete workers. Im a 3rd generation concrete man, my father has a poured wall and waterproofing business and i have a flat work company and we work together almost all the time. So for 20 years, concrete is all I've known as we do the footings and walls and everything concrete for a home all the way to the final driveway and sidewalks as we offer a turnkey package here in central North Carolina. So again, thanks for the kind words and your appreciation for the hard work I do every day. We maintain a small crew and im the one who screeds, floats and trowels, so im just a higher paid laborer. Love your channel and enjoy the authentic and honest nature of your videos. Very down to earth and true to all of the trades. Keep up the great content.

@chrisbell1068 5 лет назад

I really appreciate all of the knowledge you share on your channel. I’m not sure if I’ve heard you say this but there’s a saying that goes something like, “you have two different fathers in your lifetime, your birth father and the older man you meet that teaches your all the things you desired to know about.” That’s probably far off from the words of the quote but it’s still the same message and I feel like you are that second father in a way that my father couldn’t be for whatever reason, not because he’s a bad father because he’s not but because you’ve just had a different life experience to speak of and draw wisdom from. My father was an army guy and never really did any labor jobs so the life lessons came in a different way than yours. But anyways to make a short story long, thank you and keep sharing all the knowledge you can. I learn from every little thing you say in your videos!

@xerxes456 5 лет назад

Great video............. In Scandinavia, we use a lot a concrete people would think it is high slump concrete. Self-consolidating concrete is a highly flowable type of concrete that spreads into the form without the need for mechanical vibration. Self-compacting concrete is a non-segregating concrete that is placed by means of its own weight. The importance of self-compacting concrete is that maintains all concrete’s durability and characteristics, meeting expected performance requirements. In certain instances the addition of superplasticizers and viscosity modifier are added to the mix, reducing bleeding and segregation. Concrete that segregates loses strength and results in honeycombed areas next to the formwork. A well designed SCC mix does not segregate, has high deformability and excellent stability characteristics

@alexmashkin863 5 лет назад

Great comment. I feel like I should add one thing about it, though. I don’t know a proper English term for it but in SCC you have to have carefully designed aggregates particle sizes distribution for the concrete to be able to compact properly

@murraystewartj 5 лет назад

Scott, I've had limited experience with concrete (footings, foundation and flatwork) and a good part of that was mixing it myself. One thing I know is that dealing with concrete is working with a mixture of science and dark arts. For the newbie - do research on the basics from reputable sources. Learn enough to be able to ask important questions. Be familiar with local codes and climate conditions. And if you're doing a job that's going to involve truck-loads of the stuff, take the time as early in the process as possible to develop a relationship with the customer service rep at your local batch plant. He or she knows the product, local conditions and can give great advice on estimating volume, scheduling trucks, admixtures and other arcane stuff that can make your pour a successful one.

@diamondflaw 5 лет назад

I live in Idaho... we purchased our house a couple years ago (not a lot of money, first house) and were so happy to have a place with a garage.... the thing is that we are now having exactly the problem you were talking about with the surface spalling right off in a few places as soon as some moisture came in on our vehicles this winter. We're now looking at doing some sort of patcher followed by epoxy sealer to try to protect it... but oh man I wish I'd known sooner.

@Jonesocinco 5 лет назад

You might be able to get away with doing a topcoat but even if done correctly they have a tendency to de laminate from the existing surface in high freeze climates.

I've watched all of your videos and I want to encourage you to not let any criticism or critiquing undermine your capabilities in your trade. I've watched every one of your videos and they have taught me more than you know about pride and capability, what your demeanor has brought to my life is that being pride full and proud of my work are two very different things. I'm a very proud 'blue collar' individual and your video content has provided me with another confirmation that just because you work with your hands... its a lost art that I don't see alot of support for currently and I want to rebuild the legacy of the steel toe boots or the tool belt. To me you're a bit of a 'when the going gets tough, the tough get going' so continue onward with your endeavors. to everyone else matters and situations are not the same 1000 yards from your door let alone a 100 miles... so please be a person of character and understanding and try to realize that regardless of your situation you are a person built on a foundation of which you were brought up in and sometimes the best way to look at things is with bling eyes and open ears.

Man, you've got it all! You've done a lot of work in Arizona, Phoenix area, in the past, as I've seen in your videos... I worked for Melvin Concrete (Sunnyslope) all through the '90's, our Super was a man named Karl. He worked the Hoover Dam project as a kid. When I worked there, he was 78 years old before he retired. My foreman was a Vietnam Vet with the Marines, and he spent his entire career with Melvin. We did commercial concrete all over the Sun Valley, from Sun City, Peoria, and Glendale, down to Scottsdale, Mesa, Chandler, Tempe, and Awatukee. We did the Firehouse in Tempe, the Pool facilities at Mesa High, a shopping mall in Awatukee, a Mormon Church in Glendale, a Bank of America (including the vault) and Rawhide in Chandler... Those men taught me everything I know about the trades, about concrete, and about life. Thanks for bringing it all back to me in your videos.

Good practical info. High range water reducer (plasticizers) have their place but if you buy enough concrete to have an influence with your concrete supplier the first place to go to get higher slump mixes without paying $$$ for a lot of superP is to get clean good sand and really focus on proper gradations of your finer aggregates.

@johnblock1911 5 лет назад

I worked in two pre-cast concrete Co.'s after high school. ( '72 grad.) One used wood molds, welded & tied rebar and bolted in fittings and weld plates. The 2nd was making "quad-tee" panels, a steel bed 8 ft. wide & 2 in. thick, w/4 equally spaced "legs" running the length of the bed, ( over 300 ft.) and leg depth of 12 in. Panels were seseparated by box headers threaded on the cable, with dividers. In that one, reinforcement was solid, 7- strand steel cable, from one to four cables in each leg, jacked hydraulically to 0 droop, _then_ pulled as much as 18 in. elongation, followed with #2 rebar laid across the bed as it's poured, raked out, Spud vibrated in the legs and vibrating screeds followed by finishers. Interesting work, if back-breaking. I look back at age 65 and groan.... Anyhoo, the POINT I'm going to is we had two different jobs come in at the quad-tee plant that called for - and got - 0 SLUMP POURS. The overhead crane brought the bucket out of the batch plant, positioned over the bed, and it fell out, barely plastic enough to drop verticly, and...STOPPED. Vibraters and screeds could barely work up ANY cream for the finnishers, The rakers ( I was, on one of those) were calling the batch operator and QC guys everything but a child of God, Worst jobs we ever did. But we had much use of chemicals, hot water and steam injection into the mix, cuz we ran two shifts a day for much of my time there, stripping and pouring 3 beds a shift! (We only had 4 beds in the plant!)

@bilonay 5 лет назад

Great video, thank you so much! One point to nitpick on though. You refer to viscosity as the runniness of the fluid (concrete in this instance) whereas viscosity is actually the resistance to flow/shear stress deformation so it's actually the opposite of runniness: decreased by adding water and increased in the absence of it.

@matsherwood6277 5 лет назад

We pour 6 sack limestone concrete at a 6ish slump all the time for driveways and such in Michigan and have great success and durability. A good mix doesn't have to be too crazy dry to hold up. That being said, there seems to be a fair amount of different practices in concrete work based on the weather environments.

@gabec6522 5 лет назад

Same here in Ohio and our weather is way worst then these places! I feel the trick is , is to get it flat and then finish don't mess with it and not bring all the water up as much!

@mechanicojoe 5 лет назад

Awesome to be getting some of that knowledge out there. Here in Alberta we have entrained air in the concrete to help with freeze/thaw cycles. We can't use wood bull floats/darbys or steel trowels on entrained concrete. Magnesium tools really shine in these applications. Some people use the rattlestick attachment, but we can only use it slightly to avoid bringing up the cream. So much to learn! Concrete is really cool!!

@mechanicojoe 5 лет назад

@Kurt Miller Yeah they can be used. But the proper tools are also available. Wood bull floats are good because they wont likely seal the surface trapping air and water under the paste but will have a tendency to tear the surface of entrained-air concrete. Its recommended to use a magnesium bull float on light weight and entrained air concrete. If a mag bullfloat was sealing the surface I would switch to a wood bullfloat. If I use a steel trowel on entrained air concrete I would do a single pass by hand. Ive seen troweling cause blistering, delaminations, and reduced scaling resistance. Crazing is fine but not a final product to be proud of.

As a cabinet builder and finish carpenter I have always found concrete to be an interesting thing. This video touches on the topics that I find most interesting about it. All across the country and world and different climates basically the same formula is followed while tweaking different additives and pouring techniques to make it work for them. Very interesting.

@Scott-jf1nh 4 года назад

I read a book called “Concrete Planet”, by Robert Courland. Very interesting book about the history of concrete and information about modern concrete. He said the rebar was the biggest problem with modern concrete. Iron oxidizing, swelling and cracking concrete enough for water to get in and completely wreck it. He said that another material, like some type of glass was called for if poured concrete wanted to last longer than 100 years before it fails. Almost all modern concrete fails way faster than 100 years. Roman concrete used a special ingredient that is no longer available from an ancient volcano. Love this channel and Scott Wadsworth. Thank you and your son for all the great videos.

@TheAxecutioner 5 лет назад

My friend poured the Toyota test grounds, union work, spec job. He said the crews would wear out aluminum rod boards from screeding pours so many times over and over to get it perfectly flat. Engineers all over the place making sure the specs were followed to the T. At times, I have done my best with a rake & then went right to bullfloating. The divide between those two extremes is vast, there's room on this great big planet for everything in between.

Man, you have a way with words. If you were my teacher at school i'm sure i'd be a lot better off right now! I recently poured a concrete slab over here in France for our utility room (15m2). We used a product called Lafage Sensium (www.lafarge.fr/sensium) which has the plasticiser already added to the cement. It was a real treat to work with and i believe the curing process is also accelerated allowing you to put down the finished floor sooner. I've been following you for a couple of years now and really love what you're doing here.

@conmanumber1 4 года назад

Hi from Oamaru, New Zealand. I learnt to 1. Use the absolute minimum of water and it's amazing still how much vibing will draw out water. 2, vibe to settle and increase density without porosity. 3, after setting and hardening I water for 7 days without any break in moisture. This helps the final curing process as concrete goes thru a process of chemical reactions. (however concrete takes 1 weak per Inch to dry.). I avoid additives as my brother who does civil engineering projects (Downer e.d.i Infrastructure) believe it degrades the concrete.

@chuckmiller5763 5 лет назад

In Arizona, bridges are still poured with a Bidwell machine, other drive surfaces require a roller screed, no tamping. The top surface is called the wear surface. Adding water to finish the concrete also weakens the wear surface. Some people power trowel, I am a fresno and weights finisher, with a fine broom at the end.

Great explanation. I worked a concrete job in Alaska where we jitterbugged to a glass smooth finish using plastic sheeting under the pour. Looked great but it was on a ground floor walkout level. I was totally new to concrete pours then. Still wonder how that floor is doing. Those -45 temps can be havoc on concrete. It was not a heated floor but it was a living level. Spaulting well explained...to me...Real science behind the mix. Thanks.

@aanazrel 5 лет назад

Well said, I have finished a lot of concrete in northern Wyoming and the process is deffinatly different than further south. Ground heaters and blankets, accelerators is the only way we can pour in the winter. As one of my mentors said "better living through chemistry" ... . We commonly use plastsizers in laser screed work. It is all possible with intelligent mix design and proper preparation.

I honestly hope that no one from Canada chirped you about the jitterbug or the slump. Maybe if they did it just means they have never been to a part of the world that never sees subzero temps. I am from Canada and in fact we have been in a seriously cold spell (-20 to -40 lows) most of February. You know what? Our concrete cracks too. We don't have the magic formula for concrete guys. Keep doing what you're doing EC! You're awesome.

out of curiosity while at Home Depot I checked what kind of stakes they sold... which was only round. From my experience every store has about the same things sold give or take a few regional items, thus that's why round stakes are used. They are conveniently available at the Homeless Despot.

I'm a concrete inspector in central Kansas and I also help teach ACI (American concrete institute) field testing of concrete. People are constantly amazed at how much science is involved with concrete and the tests involved. A bunch of people swear that concrete dries, when in all actuality it cures. It's a chemical reaction that produces heat, and in some cases a ton of heat. Interesting trivia fact about concrete that I use to help prove that concrete is chemical... You can kill fresh concrete immediately by adding one common household substance, and it's not water 😁... ... Sugar!!! Add a can of Coca-Cola to a wheelbarrow full and you'll never have concrete in that spot😳 I use that trick in class to make the concrete last all day during teaching, practice and testing, except I use about 1 can across 6 wheelbarrows. If you ever have a question about concrete testing, I'd be happy to help! It's about the only thing I feel proficient in 🤣 As a side note, I discovered your channel about 2 months and have lost 2 hours of sleep a night since. I got caught up on the spec house and am now going back in time through your channel. I can't thank you enough for your massive amount of experience, knowledge, and your willingness to share it with people like me!!! YOU keep up the good work 👍👍

@williesworkshop5689 5 лет назад

I have been patiently waiting for this video since I starting watching your channel. As a concrete construction inspector, I was cringing at some of those water slumps, rebar placements, and finishing techniques. This video was a good start in explaining to the viewers different aspects of concrete and concreting. Concrete technology is like any other technology. Mix designs, admixtures, & placement techniques are constantly evolving . .in a effort to make the concrete industry better. Unfortunately, most cases, the weakest link is the concrete contractor that is afraid to change means and methods with the times. You briefly touched on superplasticizers, great technology. . Highly under-used in the light commercial and residential sections of the industry. Jitterbugs, definitely not a good finishing technique, in my opinion. Pushing that coarse aggregate down into the slab not only reduces the freeze thaw durability of that surface . .but also reduces the slab's resistance to abrasion from traffic. The surface paste with minimal coarse aggregate is far less resistant to abrasion, than with the coarse aggregate. Briefly touching on the topic of slump. .W/cm ratio not only affects strength, it can also affect long term durability. Great start. Thanks again.

@saloppedisano9745 2 года назад

How is a jitterbug different from a vibratory screed in as much as both function to consolidate coarse aggregate and bring workable paste to the surface?

@stevenheinje181 5 лет назад

Not an expert in concrete but am with coatings on concrete. The curing membranes, or sealers that can be put on wet help with the freeze-thaw issue we in the north content with. Surfaces are rarely even 20% as strong as the interior of the concrete. I don’t know how much aggregate and finish impact this but I do know Often the surface has too little water. These sealers balance the release of water and give a better hydration, make strong the more like the interior, and you get a less porous surface. On the other hand I cant say for sure that applying sealer later, as maintenance, works. I seen it both ways: the sealer can hold water in which is bad when winter hits. So while I like curing membranes, maybe simply misting is better on a high water-table pour on the north. In the dessert I’d always use the curing membrane. This requires local experience. Looking at maintenance, I very much prefer the kind of product one of my competitors makes Euco Super Diamond solvent based sealer. I use it when salting is common practice. Nothing worse than salt.

I can’t believe they hand rodded that driveway off. I’m getting too old for that, if I can’t get my a-frame power screed on the pour I kind of don’t want to do it anymore. Here in South Dakota that pour would have been poured, power screeded, bull floated, edged and Fresno’d a couple of times, broomed, then cut. That’s why I love your channel, to see the way other people do things.

Super plastisers are great ways to increase slump and workability, but you should also remember that "initial set" is not reduced with the additive. When SP is added to a concrete mix, it needs to be positioned as soon as possible for a strong mix.

On the opposite end of the spectrum in Canada we have accelerator or salt that they add to the concrete mix to make it kick the water off quicker so it doesn't freeze in the winter when you're pouring concrete at -30

Please share some videos on reinforcing bars and mesh placement. Do control joints need a break in the mesh? How do you calculate the minimum thicknesses required? Would love to hear more practical examples of shrinkage and how to anticipate it. When tying into existing slabs when do you use smooth re bar and when would it be more appropriate using ribbed?

@AS-cu2rd 5 лет назад

Slump is also increased with the use of plasticizers and water reducers which don’t effect the compressive strength.

Honestly, I would probably let a 6" slump pump mix ride, especially if sampled from the tailgate. It will lose some slump through the pump, and it tends to be juiced with extra cement as you said. For 95+ percent of the time, the worst thing that can happen is it'll be on the discrepancy list until the 28 day breaks come up 150% of compressive strength.

@thenetwerx 5 лет назад

I live in a cold freeze thaw zone in the Midwest the primary problem with exterior concrete in this area is stone aggregate itself . Some of the stone close to the surface absorbs water and freezes expands and causes a spall in the surface outlining the piece of aggregate exactly. I think It might be better as long as the cement water ratio and proper air entrainment (jitterbugging) won't necessarily be harm
