What would you do?

Sometimes things don't go as planned when pouring out concrete. There are so many varables to the finish product. You have to be ready to make quick decisions to get the best results. See how this one pans out.

The best part about this video is you guys were helping out a buddy (that's "mate" for you guys down under) for no financial gain. We need more of this. He must be a really good guy for you guys to do that for him. I've done concrete work for a friend before and it doesn't make it any easier. In my half a century plus years of messing with concrete I've learned this 'There is an easy way to place and finnish concrete and there is a hard way and they're both hard.' Nice job.

Thanks Kris. I agree they're both hard. LOL. Yes we have an awesome group of friends.

[@henryjohnson3851]

One thing for sure, once you start leveling it off you cant reject it. Bad though when getting multiple truckloads and not similar water content, especially on poly. .That conveyor setup is great. Never had those back in the day. Really great too that you have lots of help. I was never so fortunate, usually just myself and a flunky...... Good job guys

[@bondobuilt386]

Thanks and I agree. Yes this truck is so helpful 👍

[@nonyabuisness]

I carry fritz packs on my truck. They have a product called sump buster that will reduce the slump. They also have air down, air up and a super plastisizer.

[@bondobuilt386]

Yes that's a good idea to carry some with ya for these problems that come up.

[@akdefense]

Reject the mud! Most of our S.O.G. and suspended slabs we broke down into 200cu.yd sections, we needed good mud. Usually 3 - 4 slump with glenium added bringing it down to a 5 slump. The superplasticizers are the way to go, added on sight just before the pour. Goes in smooth and fires off quick. It would take a little under two hours to place, usually in less than 4 hours from the start of the pour your done finishing it. All flatwork like this we'd keep 5 minutes between trucks. As for ceilings, walls & columns, we space trucks 15 minutes apart. This was in the Anchorage, Alaska area, we poured year round. Most trucks were tested, slump and cylinders. Keep some paver forms, deadman forms, flowerpot forms around for those days when you end of with extra mud:)

[@bondobuilt386]

I have used the super P concrete and it is the way to go. This concrete plant is developing a special mix for me but its gonna be a bit before I trust it on a bigger pour.

[@scottjones8036]

I have been in the concrete fiber business for over 20 years. In that time I have worked on a lot of very large industrial floors with steel fibers and polypropylene fibers. My question is why is the vapor barrier on top of the welded wire? Doing that makes your welded wire useless in the slab. The wire should be positioned in the top 3rd of the concrete to get any benefits out of it. And than it needs to be up on slab bolsters to achieve that. Wire in the bottom on the slab serves no purpose. Just a waste of money, time and labor.

[@christophersleight19]

It looks like the wire is on top to me. But, I'm not a concrete guy.

[@concreter6832]

In Australia mesh is to be approximately 35mm from top of concrete, not down on the bottom, unless U had 2 layers , the inspectors would make us use plastic chairs under mesh , that way mesh will sit nice and level and in the correct height,. Chairs for that job cost $50 . Everyone does things differently.

[@deanevangelista6359]

I’m sure the wire was pulled, but with that soup, it may sink too low.

[@tonygolledge7906]

Yeah, ware are the bar stools hey ?

[@nieldcreek2098]

It’s so hard to pull the trigger on sending it back be cause it just screws up the whole day. I think letting it set for 30-40 minutes before screeding ( I think in your area you call it “striking”?). I’ve been there cause it’s a hard decision, but I think you made the right choice. Fortunately you do have visqueen under it so it will force the moisture out the top so it hopefully will minimize shrinking cracks. Btw we seldom use a moisture barrier in our area, unless it’s on a commercial job. Personally I hate it cause it causes it to act up sometime, as well as take longer to set. The worse part is when you have interior mono footings, it tends to set up slower and causes a little hump in it quite often. Nice job, you made the right decision in my opinion.

[@bondobuilt386]

Thanks for the comment. Looking back maybe I should have kept the first truck low and dumped second on top of it but that slows down getting it all in and this was a big floor. If we dont use plastic inside buildings here they sweat terrible and your tools will rust. 👎 Happy pouring my friend 😊

[@deharts4]

It’s nice that you talked about pulling up the wire mesh. If it was dobie or chaired up it would have given the concrete the strength it was intended and since the concrete was delivered wet you lost more strength. Every job should have dobies. If it was a commercial build it would not pass inspection.

[@bondobuilt386]

I find it dangerous to walk on chaired up wire mesh.

[@larryag99]

You can always add water, but you can't remove it. Order with 3 or 4 slump and add water on site to suite.

[@ericbizzell7432]

You should have just unloaded the second truck first, while the first one sat with its drum not turning. Within half an hour it would have droped half to one inch slump. I'm a concrete driver thats been laying, pumping and driving concrete trucks for over twenty years. As for any weakness worries...Don't. First of its a slab, secondly its indoors so the sun's heat won't cause expansion, thereby cracking. Also, 4000 psi is more then enough then what was needed unless the owner is planning to have heavy equipment or machinery on the slab. Yes, I understand it takes more time finish the slab as you wait, but as for the end product there will be no problems.

[@bondobuilt386]

Thanks Eric. Good info thanks for sharing.

[@jayphillips4058]

Concur..let the first one cook if the second one isn't distanced too far. And if you do get wet/dry loads happening, always have power trowels/kneeboards split up to where you can access either side of the slab 'just in case'. The worst, of course, is having a combination of trucks with varying slumps and having a dryer slump happen in the middle of the pour, can't access that area with a power trowel without making a mess taking it through the wetter areas. Whoever's batching ought to realize if they're dealing with wet sand, which is the usual cause of wet loads, adjust head water accordingly and not have the problem. That's the thing about mud, you can always add water, but you can't take it out. Fritz packs, etc. are fine, but that water's still in the load, and it'll come back to haunt during the finish process. Or later when breaking strength cylinders.

[@ericbizzell7432]

@@jayphillips4058 Agreed, Also fritz pack? I'm presuming you are refering to dry pack or balls. Never heard it called "fritz". Learned a good trick to break them up during my pumping years. If you put two or three, 3-4 ft 2x4 boards in the load and give a good mix it will break most of the balls up without damaging the trucks fins and are easy to get back out.

Pouring foundations, we had this very problem, and yes, our lead rejected the concrete, held us up an entire day. But if we had poured the foundation, it might have been soup for half the day, and also been weaker. The mix is critical for strength, not just how it behaves while you are leveling and skreeding it. Nothing is worse for the concrete production company than to get a rejection. When that happens, big heads are talking.

Since it's not slump tested any liability falls on the contractor, and you said it was a friends (residential) so it's his $$ and your expertise.

Even if the homeowner is able to find a competent concrete outfit, it seems something always goes wrong anyway. I've only hired a few jobs (different companies) and each time faced one if not three or four disasters. Like this: Needed a 22x36 monolithic slab with footing for a 2-storey building not yet built. First disaster was the inspector arrived and demanded a much deeper18" footing, so they had to redig after level sand was all ready in the middle. The boss said "there goes the profit" because we had agreed on a price. I had to pay more anyway. Next disaster was the concrete supply company gives their real attention to commercial jobs, and probably mistreats homeowners. So they held me off a few weeks while winter approached, finally arriving on a Friday (end of week, not clean fresh concrete). Since truck could not reach my site, I had to pay separate company with a pumping machine. We started, and after 6 yards the pumping became impossible because the batch contained big hard clumps. So the pumping guy said "I'm not ruining my new $60,000 machine on bad concrete", and he just drove off to the next job. He got fully paid anyway because of his "minimum". My guys had no choice but to hand-shovel 6 yards of concrete out to middle of my back driveway, one wheelbarrow at a time. In doing this, they chopped up the nice 6mil plastic on bottom, so it was no longer waterproof. Foreman had to churn all the concrete with his bobcat to mix it with earth to avoid a gigantic mountain of concrete drying. There went my monolithic pour, since the foundation was poured and slab had to be done the next week. Everything went wrong, and nobody (including me) was happy. Things look peachy keen on youtube, but try hiring a concrete job in real life. I've had many other big problems on other jobs, each time different and unexpected. No amount of "better planning" would have helped. One of the biggest wildcards is the concrete supplier. The clock is ticking and you get stuck with what they send you. The only remedy is to be a big commercial outfit, where everyone knows they better treat you right, as it affects getting future work. Homeowners are the lowest priority and nobody cares.

Who performed the slump test? Should have rejected if out of spec.

[@SM-xm7dt]

How is it that concrete is mixed wrong? Don’t the concrete plants weigh everything to a formula? Is it human error?

[@bondobuilt386]

It was the driver adding to much water to the load. They fine tune the slump in the truck. The Aggragates can be dry or wet if they got rained on so they need to adjust things.

Back in the 80s I drove mixer for fl mining and materials in ft Myers if we had a reject load the plant would fix load send it new job new ticket same for state dot mix they new ticket go across the street to our dot prestess and pour columns which hold up fl bridges nice hun!

[@GetTheNet1963]

mixed the wet with the other trucks.. don't park heavy trucks on the wet area. It will splinter quickly.

[@jasonharper2601]

why did you not reject a load if we get the mud out of spec it goes back

[@cheshstyles]

Add slumpbuster ;) I order it drier than I want to pour by 1 number (usually i order a 4 and pour a 5 unless it's small, cold, or a lot of pitch

[@GRUBB-MUDD]

U guys use vibe strikes?

[@bondobuilt386]

I like to pour at a 5-1/2 to 6" slump. I will have to get some slump buster. thank you 👊

[@cheshstyles]

@@GRUBB-MUDD no we do pretty small pours, 2 man aluminum screed, terrible puddlers 🤪. I like the Australian style one man screeds Concrete ninja uses but the aluminum ones are useful for other things as well and I don't want to carry around 2 types

[@GRUBB-MUDD]

Man I used a viberstrike today, and it was only 13 yards maybe 14 and it was hump day! Good thing I had that Cadillac Concrete Products bullfloat

Looks great but I wonder why people want pads so thick ? I guess they think it’ll be better I think 4” pads last the longest myself.

[@clydesolomon8533]

You done the right thing, if you had sent it back it would have messed up the whole job as far as timing !

[@bondobuilt386]

I agree only thing I might change is to keep that first truck low and dump over it with the second truck.

[@brucerazor5202]

Not bad you don’t see to many old concrete finishers

[@twinge2254]

Would've bottomed out 2" with the wet stuff and topped off with the good stuff if it was feasible.

[@seanmayo206]

Gonna be there awhile

[@tomscott4723]

Self-leveling! That will put u out of business, all the DIY'rs can just dump it in the forms right? haha Just another day at the office.

[@bondobuilt386]

Yup shit happens Tom. LOL DIY would be tough on this big floor. 😊

[@Stacked3403]

I've tore out a lot of concrete and almost every slab with mesh it's on the bottom not doing anything or in the dirt all rusted out. I'm just curious why you use mesh as opposed to steel or fiberglass rebar? I know everyone is different in how and why they do stuff just wondering. Good job by the way

[@josesoares1245]

Because it is a fraction of the cost and significantly cheaper to install when you factor in labour costs. Any concrete company worth a damn uses rebar reinforcement. Mesh is a cheap man's material nothing more nothing less.

[@bondobuilt386]

We have to be competitive with cost. The mesh and fibers are above the building code. They would just hire someone else because they were cheaper.

[@bondobuilt386]

@@josesoares1245 I use bar where the homeowner is willing to pay the extra. Most are looking at the cost and it is already above code with wire and fibers.

[@thomasnickerson9258]

Always check the slump, before you dump.

[@sjones8738]

Why pour concrete for half of the building? It make sense to cover the entire area with concrete to avoid cracking along the edges.

[@metalrooves3651]

what? cracking along the edges? The guy couldnt afford it maybe..or maybe later...why would you second guess THAT decision?

[@TheLarson25]

do a slump test and verify whether the mud can hold up

[@idadho]

What if you poured the first load thin, maybe only 2 inches then topped it with stiffer concrete? That sloppy mess would cold joint fine.

[@bondobuilt386]

Yes we could have done that. 👍

[@gunfisher4661]

get some bags of dry Portland mix and spread it around and work it in with the power trowels.

[@idadho]

@@gunfisher4661 That would be fine in the truck if it was added before 90 minutes 270 turns were elapsed since batching but would never get a proper mix in the pour.

[@xmasbruvsgaming8234]

Where are ur conc chairs, mesh doesnt do anything on the bottom

[@rodm5830]

Throw a couple boxes of saltines in the first truck, dry that mud up a bit.

[@johngoogle7626]

Did the cement company offer you a discount on that first truck?

[@williamcordle-FLman]

I’ve rejected mud before but it was a big condo job where we were flying it by tower crane in 3 yard buckets the had brought us a truck load of gray water and wet rocks the driver had left the water valve on we normally ran around a 6” slump on flat and ran a little drier slump on the vertical walls so the rocks don’t settle as much

[@jeffsedletzeck3882]

Check out Super Slump Buster by Fritz Pak

[@bondobuilt386]

Thanks Jeff I will check that out.

[@robertmccully2792]

How much water did it leave the plant with? On all my big jobs there were special inspections so would have had to reject. But to let them get away with this is a crime in itself.

[@christopherhaak9824]

There should be a mix load ticket for the truck from the batch plant. That is a must for any inspected work like typical Gov. jobs, so you could check that. The hassle of the load rejection is all on the batch plant.

[@mariorivas3687]

Water reducer and 7 Slump no problem 😉

I guess when the floor cracks and your new dump truck takes a dump the concrete salesman will still be eating steak due to good intentions.
