It's concrete day!

 

[MoparMitch]

Awesome Dave. How many yards of concrete does it call for?

 

[Gpuller]

What is the cost/yard now days?

 

[super-bee_ski]

I just poured 20 yards...
Approx $80 per yard here in CA

I imagine Dave's pour is about 100 yards...

 

[khryslerkid]

I want to see some wood!

Sounds cheap. Want to say it was over $125 a few years ago here in MN.

 

[northerndave]

I believe we poured about 53 yds today. I'll post pics tomorrow.

The ball is finally moving.

The crew started the pour with the edges where the slab is thicker.

they used a boom truck with a remote telescoping belt that fed the concrete out to a drop chute. The owner of the truck walked around the outside of the pour and controlled exactly where the mix was dropping in. He had a wireless remote on his belt that controlled the swing, extension, feed rate, height etc. He also has an alarm button to signal to the concrete truck when to stop and start feeding the boom truck with each load of concrete that came.

Partial pour complete here, screeding with a 12' vibratory screed.

A couple of power trowels are finishing the top here.

I also got my rafters yesterday.

now we will start seeing some progress.

 

[mopar4don]

Nice!

 

[super-bee_ski]

Dave,
It's all looking good!
You must be excited!

PS: thats a big pour!

 

[northerndave]

Trouble with my slab. The finish is messed up. It's very patchy with loose flaky areas.

I'm pretty sick about it.

Concrete guys are coming to look tomorrow. I sent them pictures already.

I just really didn't need another setback.

This sucks so bad.

 

[MT_Mopar]

Damn Dave, sorry to hear that, they will fix it for you.

Everything is going to be OK buddy.

Keep us posted

Looking at a couple of solutions.

it's early yet in the whole analysis, but I think the most likely solution will involve repairing the patches that are showing the spalling, then having a professional epoxy job done to the whole floor.

Not a home depot do it yourself job, the real deal with the shot blast prep and multi stage coating, the thick stuff.

We'll see.

I did that to my floor for the same reasons, if you have any questions, let me know.

And the concrete supplier is paying...

I'll PM you, thanks very much.

Any indications on what caused the problem in the first place?

 

[northerndave]

Top skinned over too fast, areas where the cream layer got "burned" the surface was too tight, water was still trying too bleed out but couldn't breathe through those burned spots. So, it basically blistered the cream layer loose.

Something like that.

That's basically the best theory right now and my own impression from what I've gathered.

The concrete guys are looking towards the company that supplies them with mix powder, thinking something caught them off guard with the condition or age of the powder itself that lead to a "hot mix".

These guys batch a good volume on a daily basis, they aren't what you'd call a now and then small time operation. One of the crew guys is a friend of mine, he came out to look this morning. He said he's been doing this for 20 yrs and he's only seen this happen once before.


I guess I'm just lucky as phuck huh?

"WE" (Air Force) had an EPOXY job done here at one of the hangars....
YUP, it's not the stuff you can buy at Home Depot/Lowes.
Tremendous finish! You will love it.
It's thick, durable and chip resistant and aso resiliant to oils/chemicals

 

[northerndave]

Well guys, it looks like they will be chipping loose the flaky spots, prepping the existing slab, applying a crazy bonding agent with brooms (paste like).

And then pouring a 2" cap with fiber mesh.

That is the recommendation from Lafarge.

Sigh...

Ok.... set back another week before walls can go up.
