Construction thread... Show off your work!

I was at a construction leadership class and the biggest obstacle for our industry in the future is going to be finding qualified workers. For every 3 retiring there is only 1 filling the position.

Form work carpenters are a niche skill. You have to be talented and resourceful. A lot of it is problem solving especially on remodels.

Yes they are cool ties, they get greased up before and spun out after it sets up. Also drop anchors wiith coil rod for uplift in the existing footing.

I like to call it spray form lol, couldn't live without it or there would be a hell of a mess for clean up.

On tight pours with tough access I use a mix with super plasticyser. Usually a 6 slump. Anything without cant be over a 4.

Concrete is a stressful material. The old timers have a saying g that "concrete waits for no man" meaning u get one chance and it sets fast. You better have your shit together. If not it is a COSTLY mistake. Have I told you how much I hate concrete pumps or pump trucks. When shit goes bad it goes epicly wrong.
yeh i agree with what you say we have the same issue in australia with the young generation. i found the biggest issue is the young fellas dont give a fuck, they have no passion, no pride in there work and most of all no fucking back bones.. they cant even carry timber on there shoulders lol

hahaah spray form man thats the best thing ive ever heard.. i will be using that one, ive used a similar set up with those ties, but we use Z-bars and reverse a nut onto the reo bar, then wrap the Z-bar in denzo tape so it can strip out

haha im with you on the concrete fever mate, once u start its game on and i personally think its worse when you have formwork issues and u can get the concretors to slow down on the pour while u make adjustments, then u tell them to ease up on the vibe, but nah they just drop it in and try to bust your former.

when i was in darwin we was pouring some very tight spots, we used a mix full of plasticisers and instead of doin a slump test we did a spread test. so the cone u use for slump tests, turn that upside down fill with concrete then lift up as normal, but the concrete spreads (looks like a pizza base) and it had to spread into a circle between 600mm- 700mm (idealy 650mm spread)
 
Nice! You finish concrete to?
Did you finish all of it by hand?

It's funny I used to work as many hours as possible when i was paid hourly. At the job or on the side. Since I became salary I try to work as little as possible. It really does change you.

yeh i finish concrete aswell, rather just screed and labour then piss off if i can lol but i do finish. thats a machine finish, just not burnt up. we call it carpark finish. still had to hand finish the perimeter tho. $350 cash for 6 hours work im not goin to complain. i try to do 2 a week while im home from shutdowns just to pay for food n a few bills. then all the coin i earnt away goes on my house loan

the old bloke who formed up the slab had this home made bracing system. i really like it. ive seen similar but not home made like this 1CCE2B4C-0131-48CD-88B2-1BC27A6391FD.jpeg

yeh if i was salary i would be doin the absolute minimum aswell lol i dont think i could do salary in construction or thru summer i feel its the season for overtime and thats when u make the coin. pour dates never change as u know the hours just increase to get it done in time
 
Got a question for some of you cement guys. It’s a small front yard project. See pic of area planned below:

The area between columns is 3’ x 13.9’ or 42.7 sq feet.

The next area is 8.5’ x 9’ or 76.5 sw feet.

I was thinking pre-mix bags of cement. My questing is should I get some sand as well if is the ore-mex adequate?

Thanks y’all.

im not sure what you guys have availabe where you live but i can go to the local landscaping shop nesr my house and buy 'concrete mix' which has all the stone and sand pre mixed then all i got to do is buy bags of cement and at that with water

doin the maths on your measurements you need roughly 1.2m3 of concrete(thats allowing 100mm (4inchs) depth. if you was to buy bags at 20kg you need a shit load. could you not order 1.2m3 from your local bath plant? also by the time you fucked around mixing and placing u may be chasing ur tail trying to get a good finish on it if your inexprienced.

i found that pre-mix bags of conrete go off very fast. there good for fence posts etc but i would do a small slab like that with them
 
i started to build a deck at home the other day, will finish it when im home next

i got the concrete for nothing, rang my mate at the local batch plant around 2pm when i know jobs are finishing and asked if there was any trucks on the road with leftovers. got 2 different trucks sent up. used roughly 1m3 for the holes i dug them extra deep hoping i would grt lucky on the concrete lol ended up getting 40mpa crete aswell

Have a little experience with cinder block and 4’ slabs. I totally forgot about 4” depth. Would 2 or 3” deep crack on an area not high traffic, if any for that matter?

20kg bags, that’s what, 40lb bag? The Lowe’s my way has 80 pound bags. I have a small trailer to haul with.

The chasing you tail part, you talking about the cement drying too soon?

You have a nice home @kap73,
I pour concrete for a living (flat work and decorative) the trucks where I’m at are front load, the driver never has to get out of the truck only to put on chutes and wash out.

personally i wouldnt got less then 4inchs but thats just me.. i normally go 5inchs for my own stuff because the money i save on labour i beef up my quality. 3inch would prob be ok to be honest even tho i would never do that

so 80pound(40kg) bags what are they worth?? 1m3 of concrete approx 2300kg-2500kg.. so if u need 1.2m3 approx
maths
2300kg x 1.2= 2760kg
2760kg / 40kg = 69 bags

thats a rough quote on weight. obviously thats not allowing water weight. find out price per bag, then ring batch plant and get price for 1.2m3 and see the difference. if its only a $20-$30 difference then for less work and fuel it may be easier to get it batched

yeh and by chasing your tail thats what i mean, but if u piss it right up (make it wet as) u will be fine

thanks mate, i love my house.. soon it will be even better


im guessing your american? ive seen on youtube how thwy have there chutes on the front. i bet its alot easier
 
Yes sir, I’m from USA. I’ve never used a rear end truck so I don’t know how to compare the two. I have a buddy that says he likes the chutes coming out of the back the best.

did u do the finish on that? looks like an intense job

i think both trucks would have there qualities. our biggest trucks hold 7m3 of crete, one problem with the rear shute trucks (not a common one but it happens) driving up very steep hills theres been times where the mix ran out the back of the bowl

Yes I poured and finished that, pecan color concrete with charcoal antiqued powder release.
Our trucks will hold up to 14.75 cubic yards but state law only allows them to haul 10 yards at a time.
My buddy says the guys that operate the rear trucks usually are more precise and do a better job where as front load drivers are lazy and tend to either pile it up or come up to short

thats a great job mate, u should be proud of the quality work you do

thats alot of concrete (roughly 10 cubic metres) around 23tonne in a truck

we normally operate the barrel with a controller and all the driver has to do is move forward when we say
