fly ash

[airduster29]

some one told me you can use fly ash as concrete and is much cheaper without mixing it with concrete anyone know anything about this stuff?

[halfbreed]

  haven't heard of it what do they do burn flys lol ?

[mattr]

They use it for building roads and for flocking cuttings in the oilfield. I can't answer your question though.

[airduster29]

I know alot of concret places already use it in the mix to save their cost and that it is left over from burning coal I just dont know if you can use it alone ?

[mattr]

I can't imagine that you can mix it alone. We mix it on our rig and Ive never seen it set up when it was mixed with cuttings.

know a guy that put down in front of his working pens and it got hard eventually.  he didnt add anything to it.  just fly ash thats it.  it was a muddy mess for a few good rains but set up good once it settled.

I work for power company and they get from one of our coal burning units. They mix with water and when it setsup it is as hard as cemet. They have used to repair the roads in the plant

I just talked to a guy that sales it here he said it will not set up extreamly hard it is more like blue rock or for us clechie you can mix it with concrete for a suplment he recomended useing 30% fly ash but it sets up extreaml fast and hard to smooth out if pooring a big area, it is good to use in concrete in cold weather as it wont allow the freeze to affect set up it is $300 a ton plus shipping if needed

Steven,
We have in the passed used it here on the ranch when they were giveing it away just to get it hauled off but now they sell most to concrete co.  Have a road that was put in, nothing mixed and 15 years later still great.  Will pack down and get hard.

Also the two pups are doing great.

I work @ power plant & we have the bottom & top ash.... Top Ash good 4 yr drive ways & give it some time 2 rain & it will harden up good....

We put some down on a dairy I worked on in Iowa, it worked real well if put in right, if not its a disaster.  Recently however there has been talk about it becoming a hazardous substance.  I would not recommend messing with it if that were the case.

$ 7.00 a yard

I work at a power plant and if u mix the flyash and bottomash about 50/50 it will set up hard, but when u put it whare ever u want it you have to keep it watered and packed for it to set up, the only problem with it before it sets up is it has a lot of sulfer that will rake havick on metal, it will eat the frame off of a mule in about 2-3 years

Yes but it has to be the higher grade and be careful where you put it. If you look at the MSDS sheet it has high levels of arsenic.

Flyash is good when mixed into a sandy soil as a binding agent... Used in concrete it is nothing more than a filler to cheapin up the mix. It WILL cause the concrete to set up very slow at 30% ash. If u use it just poured out on top of the dirt you have a powder that really aint good for much unless you mix it into your subgrade. It does little to nothing on clay subgrade, if dealing with clay you need to use lime as a binder.

[airduster29]

That's good to know I think I will mix it with some concrete I found a contractor that told me how to mix for best use

Mr  Mason,  good to hear mine are also doing very well
