>nooo you dont understand the science behind the concreterino you just pour it and smooth it out. literal third worlders who cant speak english can pour and work with this shitcan brainlets explain this to me? the literal only difficulty is choosing the mix. actually excavating and pouring is baby shit.
Mortar, self leveler, thinset, vinyl patch, stucco, eifs, plaster. Polishing, min/max cure time, max and min hydration respective of results, reinforcement, lime, pozzolans, glass fiber, float choice, tuck pointing, muriatic acid
>>2860148Fucj that shit. Put some more water in it.
>the 3rd worlders in question
>>2860154https://m.youtube.com/watch?v=IocCC1-jeTY
i think they mean like making concrete shapes for tiles and wall decorations or something like that.
>>2860149Too much water can reduce the strength of the concrete. Concrete doesn't dry, it cures, so the ratio of water makes a difference.
Sounds about right.
they dont make concrete like they used togo into any old grocery store or building built pre 1970. go look at grandma's house old drivewayhuge, and I mean fuckhuge slabs with NO saw cuts, and not ONE crackpost 1970s shit is cucked because they were forced to make it shitty after the oil crisis and once they realized how much money they could make they left it enshittified
>>2860144not needing english to figure shit out makes you smart though
>>2860144>why do people act like concrete is hardconcrete is hard though just try punching it
>>2860413Relief cuts weren't even a thing until the concrete became so shitty you had to put them inold 'crete:>locally sourced high quality aggregate like river stones >coarser>higher % of cement>designed to take a little longer to cure but will be strongernucrete>all coming from the same quarry in china cutting as many corners as possible>fine>limestone and fly ash added because "muh global warming" >designed to cure as quickly as possible
>>2860144You don't know what you don't know
>>2860144It can be very labor intensive if you don't have enough manpower to get across it quickly when you need to. It is more about proper timing and knowing how to work it the laziest way possible without moving it any more than needed. That's why mexicans are so good at it. They figured out how to minimalize their work input...
>>2860144I'm a carpenter but have done a decent amount of concrete. It's pretty easy to fuck up if you haven't done it before. Also hard to remove if you fuck it up. It's definitely not rocket science but I can see why it would be daunting to people with no experience in it.
>>2860435Lol mexicans are decent at concrete, they're not the amazing superheroes of concrete like America thinks they are. They just do the work and don't complain but it's not like it's at a super high level or anything.
>>2860417Concrete gets harder over time.I was trying to put in holes for anchor bolts in 100 yr old ‘crete, and it’s like porcelain.It also makes sharp chips off the top like porcelain
>>2860421Also, no or little rebar nowadays.…unless the customer is watching.Heheh… “yeah, we got lots of rebar in there, we just poured it before you got here”That’s why we pour at 5:30 am.
>>2860504yeah with the prevalence of ring cameras these days good luck with that. driveways and walkways are the number 1 pour post build for a house.Also if i dont hear my metal detector go off when i check your work youre doing it over again or youre getting your ass handed to you in small claims lol.
>>2860469The whole point of me mentioning Mexicans is because they figured out how to minimally work the concrete because they are inherently lazy. Every time I make a big pour of concrete I overdo shit and rush around getting things done because I don't have enough help and I'm wore the fuck out after it is all said and done. A crew of several Mexicans make it look easy.Pic rel is one pour I did at my farm shops. Had a couple other guys helping for a bit basically running the chute and keeping in front of the screed full. I did build a roller screed for this pour which helped a ton. I did all the bull-floating and probably 90% of the edging myself. It's easy if you have enough guys and they all have their own specific jobs that they know how to do and when to do without being told. Of course experience helps more than anything probably. I'm not used to pouring concrete, so when I do have to, it's a long day.
>>2860519That's a very nicely done slab for a guy who doesn't regularly do concrete.
I want a huge pad poured. A big one. Haven’t gotten specific quotes but it’s probably somewhere around $30k. What if I buy the materials, already have the equipment, and hire the Latinos myself? Paying 30k for some hack to middle man for me is crazy when I could probably get the materials, hire the help and pay for professional consulting for 12k
>>2860528Thanks anon, it's not perfect, but it does the job sufficiently! The previous pour next to the shop we used a vibrating screed with just a couple boards and a motor vibrating it and that one really kicked our asses... The roller screed I built was easily worth the time invested, and I have it for future projects as well... I do have more slabs to pour. Someday I'd like to put a concrete apron in front of the shop at my house, Pour a slab for a small grain bin that I will use for storage on another farm, etc. Always trying to improve stuff around here. Pic rel is the roller screed I built.
Another slab I did on the side of the shop for fuel tanks.
Freshly poured section in the shop. This side of the shop was previously a dirt floor so we dug it down and poured concrete. Also shows the version one screed that we used for all the interior pours and the one exterior pour.
All done with concrete inside!
>>2860539Is that a stack cruiser I spot?
>>2860559Yup. BW38
>>2860504Rebar isnt necessary in ever application and can actually make a slab fail quicker because the rebar rusts and then spalls and fucks the slab upWire mesh tho? Yeah you need that shit every time.
>>2860519> Mexicans is because they figured out how to minimally work the concreteIt makes me sad that you really believe that.
>>2860689>It makes me sad that you really believe that.Its true. Watch someone who has never poured concrete or who is really rusty at it. They will end up moving 3x the amount of concrete than the mexican crew does. They put it where it needs to go with the truck and move the absolute minimal amount around by hand. Now guess which guy is going to be wore the hell out at the end of the pour?
>>2860540Youre pouring directly on mud?
>>2860829>Youre pouring directly on mud?Class 7 road base. Shit gets hard as concrete when packed tightly. We hauled probably 150 gravel truck (7 yards or so) loads of the stuff in to level the pad for the shop when we put it up. And another 200 or so loads for the hayshed behind it... My old man was loading trucks at the stockpile with the loader and we were running two old ford gravel trucks. I'd haul one down and dump it while he filled the other one back up. I'd get back up there with the empty truck and hop in the full one and just keep going. Pic rel is one of the trucks and a different pad I was in the process of hauling in for the shop at my place.
>>2860181Exactly. You'll spec all this shit then your laborers will collapse your e tire project because you tried to use a unicorn blend of concrete If it doesn't collapse its just because you over engineered it to begin with
>>2860924>Exactly. You'll spec all this shit then your laborers will collapse your e tire project because you tried to use a unicorn blend of concrete>If it doesn't collapse its just because you over engineered it to begin withAnd to that the mexican says, "Too stiff, add another 50 gallons" to the concrete truck driver...
>>2860144what makes you think 1st worlders are intelligent
>>2860689illegals do awful work 99 percent of the time. even if i grant anchor babies as a concession they do awful work as well. you can see it in the trades and construction practices. im in florida and all the work is worse than bare minimum. new construction or not. they cant even do gutters or drywall right. the only crews of illegals that kinda pass off middling work are ones with a white guy or two that slave drives them and makes them do it right. i have to specifically ask contractors what crews they run and do the work so i can be sure it's done right. i couldn't even get a cyclone fence done right with illegals. i know through personal experience on several jobs over the last twenty years. it also is a huge mea culpa from me to my friends out in the southwest that i know moved out there and have warned me about this shit for years.
>>2860160>>like a rawkFucking origin story right here for current US wankpanzers & their self-important operatorsNonetheless I still stood at military attention for this entire commercial
>>2860421>river stones>coarser
>>2861461Whatever he's trying to say he's true, that old concrete that used a bunch of small riverstones was ridiculously strong.
>>2861468Its really dark grey or almost bluish too. And yeah its the good shit. Probably just a lot higher cement percentage and less water in the mix is the main difference and cured for however many years in a damp location... My old man put some drypack concrete with the absolute minimal amount of water in it to get it to stick together up under a door threshold to seal it up and packed it in there real tight with a dowel and years later when we tore that door out to replace it, that concrete was ridiculously strong and hard.
>>2860148Steel fibers makes resistive heated concrete, parfin wax makes self healing/heating concrete for a few years.
>>2861468I live near a chain grocery store that used to be some older store built in the 60s and this year they remodeled the floor and went from those vinyl tiles to polished concrete and the floor looks amazing now you can see the riverstones in it, it almost looks like terrazzo. But its' not terrazzo its just the river stone aggregate.And like that one guy said, there are no relief cuts anywhere. There's like...two cracks in the whole store otherwise its one giant concrete pour. The shit is as hard as porcelain. I'm so jelly. I shop there just to look at the floor. Modern polished concrete (like youd see in home depot/lowes) doesn't look nearly as good and isnt hard like porcelain.Where did we go wrong
>>2860144>concrete not hardConcrete is very hard once cured.
>>2860666Ok then I want stainless rebar
>>2860144Concrete has a very limited window to finish.Concrete can go bad.
>>2861658The owner of a group of companies I'm under did this in his new home build. It included months of litigation with the first concrete contractors having aggregate and cracking issues. I get it, but I don't get it.
>>2861658When I was a kid there was an old 70s roller skate place near me. Entire 30x90 thing was one huge slab of dark polished concrete, without a single crack or seam
>>2860154I actually saw someone transporting wet manure in their pickup. It stank to high heavens and it was constantly leaking as they droveWhy would anyone do that?
>>2860421The stuff I haul every day has almost 400lbs of cement per yard for our standard 3000psi mix (actually breaks closer to 500+), all of our sand comes from 90 minutes away and all of our rocks come from quarries our parent company owns less than 40 minutes away. Nobody hear puts cuts in fucking slabs
>>2860421>fly ash added because muh global warmingFly ash comes from coal plants you full retard. Finishers order mixes with it in the summer because it helps slow it down some
>>2860144lmao i've never heard anybody that does concrete say concrete is hard labor if anything its the opposite. I think you've been listening to too much white ppl on here
>>2860421Wait you think concrete is made in Chinese quarries rather than the nearest one to the plant? Are you pants on head?
