I know I bought this up before but what procedures are you doing when taking out these product? How will we know if fly ash and family is presented in a products. Do we need to prepare for this? What are you doing when grinding or shot blasting buildings?
Look under Other Protective Clothing or Equipment

I'm sure fly ash is in many products...
It does have a place in manufacturing.
A little is good, but more than that is not good.

This all started back in January 18, 2002
Ray fly ash is a good thing, but how much is safe and do we need to know how to professional deal with the take up and disposal safely?
I know fly ash is in other products like wood stains, all kinds of sealers and even covered up under farm lands. From what I under stand they took these product from the landfills because it was hurting our environment, so they made new landfills with water so they could submerge it under the water. The products are safe as long as there not in the form of dust however the dust can cause cancer and other health problems. As I said how much is to much and how do we know if it is in the product?

I'm sure the color of the slab will be affected by use of fly ash...??
Other than pH and Moisture tests, there is nothing you can do.
I can see slabs being more permeable with FLY ash as well....Allowing more water vapor through the slab the cement concrete...
40% is just too much, me thinks.
I'm hoping they do tests on Flexural strength, but I think they will only do bonding...
that is floor people for ya,,, only look at what concerns them on the day of installation...

Ray when the professional floor tester guy goes out to check the ph and moister test, they can glue a swatch to the floor so the flooring installer guy can pull it up, if its stuck then lay floor. If it comes off easy then you stop and alternative methods are used.
They say between 30 0/0 to 40 0/0 is the normal.
Flexural strength is the concrete industry problem. The flooring industry has there on problems to deal with. Unless your thinking week concrete is going to accelerate moister or ph in some way.

In still another aspect, the present invention is a process for preparing a carpet having a polyurethane backing comprising the steps: (1) applying at least one layer of a polyurethane-forming composition to a carpet substrate, wherein the polyurethane- forming composition includes fly ash; and (2) curing the polyurethane-forming composition to form a tack-free polyurethane backing. Applicant has developed a process for preparing a polyurethane composition which incorporates fly ash as a filler material. The process of the present invention can result in an improved process, including increased flow of a polyurethane composition into the backstitch of a carpet. and increased pot life of a polyurethane composition. The use of fly ash as filler reduces pilling and fuzzing of the carpet face, improves flexibility of the carpet during installation, and also reduces puddle gellation during application of a polyurethane- forming composition. In addition, fly ash can be included at a higher loading than conventional fillers, without detriment to established process parameters or to the physical properties of a polyurethane carpet backing.
least 75 percent of the filler, and even more preferably at least 90 percent of the filler used in the present invention. Most preferably fly ash makes up substantially all of the filler material, that is at least 99 percent of the filler is fly ash.
How much is to much?

Flex strength gives the concrete the ability to shrink and swell during seasonal changes and cure (dry) with minimum cracking and crazing. Houses move, concrete moves and they must move without falling down, cracking, ect.
Wood has great flex strength.

That was very interesting, thank you for pointing me in the right direction.
