I was at a poor like this in Houston,Tx. Pouring Discovery Tower's basement. We worked from Saturday night till Sunday morning. Took good care of us. I drove for Cemex.
@ charles lane these trucks haul 9 cubic metres wich is 11.8 cubic yards. There is no tag axle. They are called twin steers and the spread on the rears is 72" for an average total of 80,000lbs gvrw. We now have twin steers with an additional rear tag to carry 16 cubic yards with a total gvwr of 105,600lbs. Toronto On. area is one of the busiest markets for concrete right now with +150 condo towers being built.
that's a serious mixer truck. I work for one of the largest aggregate companies in the world and we have 18 wheel mixers 11 yard drums, but then we have messed up bridge laws in the US so no matter how many axels you have you can still be in violation
This stuff is actually really strong. I break cylinders of this stuff all the time well over 6000psi. Also it only looks like soup when its moving. Soon as this stuff is placed it almost immediately starts to dry up and look more like normal concrete.
@imhorney3141974 lol ... Agilia has a slump of like 24"-30". You measure how far it spreads out basically. The Agilia flows out like water, but gets just as strong as concrete normally does. It has a lot of sand in it though, so if you are pumping it through a mobile concrete pump and stop, all the Sand drops to the bottom of the pipe and you get a sand plug. As long as the concrete is moving, it stays flowable.
Those funnels along the side are a great idea, especially for a high slump like they were pouring. couple hundred bucks worth of plastic pipe a hour or so to put up, saves having to get a few more pumpers. Even a one time use they seem like they saved a lot of money.
i wouldnt call it junk. SCC has higher cracking potential because of the relatively higher paste content as compared to conventional concrete. higher paste means more shrinkage and so more prone to shrinkage cracking. and because of the high cement content, it is more prone to thermal cracking as well. but these issues can be mitigated - it's all about planning. what were the cooling methods at your project?
I wonder if they considered just building a temporary mixing plant right there on site. Seems as if that might be one way to do it. Maybe not the best way though. Thanks for posting this very interesting video.
Now imagine pouring the concrete for the Hoover Dam 45,000 pounds per square foot. Three and one-quarter million cubic yards in the dam. A total of 4,360,000 cubic yards of concrete in the dam, powerplant and appurtenant works.
That hasn't been legal since I was doing redi-mix 20 years ago. It sucks when your in a city scene & have to wash out.. Big jobs usually have a place to do it but when you're delivering to a little guy doing a sidewalk.. Sometimes we'd wash out in the back of his mason dump.
thats almost a 10 inch slump for us Americans thats wet. but then I can remember some highway jobs that called for 4 hour concrete dose on site with about 3 gallons of accelerator per yard and would turn a 3 inch slump into an 8 but you better get poured off fast. I think the mix had about 800 lbs ot powder per yard as well. did not like that job
In the U.S. Concrete is measured by the cubic yard, For flatwork, 1 yard will cover 81 sq. ft.@ 4" thick. (80 to keep it simple) The 4300 m3, is obviously metric. What is the conversion ? m3 means? Most of the mixers here haul 10 yds.legal. The mixers there are strange looking with the booster being the second steering axle. They look like they might haul around 12 yds.? The drivers ( 2 back axles) are spread pretty far apart. Also, Was this pour T-FF after it came above steel? No trowel?
hi, basically its a very high strength slurry or grout mixture, any idea what the Mpa was used, just curious, a few years ago I delivered a load for an experiment to a pre stressed plant and it from memory was 70Mpa and 600 slump or flow as someone has described, it was to cut out the vibrating on the panels being made, it didn't go ahead so I guess it was either too expensive or what ever. Cheers
I'm jealous. My factory messes up recipes all the time and, on site, we can only add water (no super is supplied for emergencies) to a certain amount before hurting the strength of the mix (too much water and the test cube breaks at 30mp when the test is for 40mp). We get so much grief from the clients for this.
@@thomashodis5740 yeah, I could run it but it would probably have to be owned by an outfit that has other income/interests since I'm sure the current cat would be pretty cut throat for a while...the gc I pour conc for now doesnt seem nearly ambitious enough to do it and we probably only average around 100cy a day between four crews ourselves.
I would love to be part of that pour but not tying all that rebar the company I work for our boss man he doesn't allow us to have tie wire guns we have to saddle tie everything by hand with lyman's pliers he's old school. I remember hearing about this. In the whole crew is like holy shit.
I work in concrete and want to know if they slumped that to a 7 or 8 with water or did they use plasticizor? That stuff was soup, how could they say it has much PSI left? Is that why it so thick and has all that steel?
This is the record??? 14 hrs to pour 4300m^3 into a pump with 120 trucks available??? What a joke… Unless they had to move that pump numerous times (like every hour) and the form crew was full of amateurs, this should have taken half the time. With 120 trucks they should have been able to keep concrete going without a single stop of the pump… I’ve seen crews do about 2000 yards in 14 hours, on the ground, with 5 trucks…. Going back-and-forth from a mobile plant… with minimal form crew size. If they had that many more trucks and more form-crew workers… they would have knocked out 4300 in no time since they could go without having to stop to reload the trucks. Yes, I know you can only pour 2 trucks at a time, usually, and 120 trucks is overkill, but this cannot actually be a record. Unless it was everyone’s first day on the job.
The newer Mack Trucks are absolute money pits. As of 2015 the king pins prematurely wear along with the stearing assembly. Absolute garbage, compared to the older pre 2000 models.
I was on that pour worked for Innocon well planed well orchestrated nice O/T paycheck for the day

I do concrete all day, come home to relax and this is what youtube recomends...
Me too.
Add mixtures allow the high slump but still high PSI. Very costly but a must.

The actual Big Pour takes place down on the corner after the concrete is in place and the finishers are still hard at work.
I love the teal color on the Innocon trucks.

Don't know about self compacting but it was sure self leveling!

Like 10"

i wonder how long it took for it to cure.
thanks for posting this
Really? Did you seal beforehand to make sure water would not run out before concrete had a chance to cure?
I'm thinking of using Agilia.
wow! and I thought laying my 5m3 single handed in ten minutes was good. That is one big pour!
Safety safety safety my ass. That guy kicked a rock at another guy. 1 min 45 sec
awesome concrete company!!! i love concrete and this video is very

Excellent pump operations..and I'm a mixer driver lol

must be nice not have to worry about formwork pressures!!
great stuff. i wish i could get my hands on the planning for this project.

Lafarge ownes Innocon.
Thats about 600 slump very nice to work with usually i pour 30 slump very thick heavy concrete

Its scc concrete. Has tons of super and cement. Its actually really strong. I break cylinders of this stuff all the time well over 6000psi
Not sure but you might want to check the math on this.
Hello sir me Mixer truck driver 10 year Experience from Bangladesh I'm interested job
I hope that slab doesn’t hold weight. With the looks of that slump.
Its SCC self-consolidating concrete thats how its meant to be - and its very strong 70+Mpa

Most likely, large amounts of super and very good aggregate/cement/water balance.
