Ray, you know what slag is. The remnants of iron ore processing. Its a glass like composite that is crushed and added not unlike fly ash. Has been used for many years in concrete with ratios like I listed above. It does the same thing as fly ash...like making it flow better, makes concrete less permeable and all that stuff.

Makes me wonder why its any different than fly ash or why there has not been any problems with this type concrete and floorcovering adhesives.

That reminds me. Didn't you write a book about concrete and flooring failures awhile back? Wasn't this in your book as well? Can you send me a copy or let us know where we can buy one?

Perhaps you could post it on floorreports.

Book never sold.
Gave it to Tim Smith in print form. That is how Gina got a copy... Then my computer crashed and I lost it.
Dummy me did not keep disc copy...

Could not get a copy back from FCITS..
oh well... life is just too short to worry about such issues of the past.

This issue started because LEEDS accepted an arbitrary number (40% fly-ash content in slabs) in offering LEEDS credits for construction companies.

The problem that those in-the-know are aware of is that no adhesive will stick to a slab that has that much fly-ash content (regardless of being broom-swept or not) and that applies to thin-set as well.

This translates into an industry nightmare where any flooring that has to be glued or thin-setted will not stay down.

This is why the controlled pours are going to be done in Dalton. To determine how much fly-ash is too much.

Stay tuned...

By the way, great article Stephen.

Gee, almost went of the top page here on this topic.

I finally posed the question on the aggregate forum and got this:

http://www.aggregateresearch.com/forum/viewmessage.aspx?MID=5800

Now I went to Lew's website and looked for the April, 08 issue and could not open it for some reason. Lew's CFR is not posted here either.

From our main page, simply click the down arrow under 'The Commercial Flooring Report' link to select the report you want to view. The April issue is there.

Darin,
flyash in concrete is "encased", would not worry about it,
again, been in there for years,
if you talk to the old concrete guys, you will find that in the last
15 to 20 years, they have cleaned up their product a lot,,,I
mean, they used to use all kinds of "bad stuff" as fillers, and
never a problem,,,,
in our industry, there are many "hot button Issues" "industry
leaders" make up to keep their names out front,,,,before all the
VOCs and EPA regulations, the adhesives would stick to
anything, but of course, they would also burn out our lungs,

it is a trade off, you are not exposed to as much harmful
chemicals, but, you have more problems, healthy lungs or
flooring that sticks without problems,,,,,I take the healthy lungs
myself,

I agree Lee, it's 'encased', so are you saying there is no need to
grind humps out of a floor, or there is no need for relieve cut in
floor. How about concrete is so hard that it will never crack. """

I hope you are using a dustless system, no matter what is in it,
OSHA regs require it if for no other reason


""""if you talk to the old concrete guys, you will find that in the

Lee your right again concrete is prefect and always has been"""".

No, it is not perfect, just better than then in terms of what they
are putting in it,,,in "past days", lot of "stuff" would go into a
batch,,,just cleaner now to help us with our "new" adhesives

""""in our industry, there are many "hot button Issues" "industry

VOCs and EPA regulations, the adhesives would stick to
anything, but of course, they would also burn out our lungs,

Lee I agree things need to be address up front and a lot sooner
than they are.
I also believe each of you men that are voicing your options are
industry leaders, how you use that power is up to you. """"

I am not, repeat, not, an industry leader, the ones who "tag"
themselves as "industry leaders" are not the leaders, just
egoistical greedy people wanting your dollar,,,I have never asked
anyone for money, well, I really would like one of those BYK full
spectrum gloss finish thickness meters, only about 5000 if you
guys don't mind chipping in for one for me,,

""""it is a trade off, you are not exposed to as much harmful
chemicals, but, you have more problems, healthy lungs or

Lee I agree again, but as you will know every thing is a trade off,
lungs, cancer, etc. choose your on poison. Safety should be
higher on the list for workers and occupants of the buildings.

ok,
there are systems, that can, make you tons of money you just have
not explored yet,
there are the ride on floor strippers, big money there,
there are the big grinding machines, dustless, that are used every
day on construction sites by floor people,
first, contact your local distributors, and see what they have, then,
contact some of the smaller commercial contractors, or the lager
stores, and offer the services,,,,only, do not go in asking for work,
go in, like, you are doing them a favor, which you are, offering
them a chance to get the job done, at your price,
have fun

they are looking for the cheap,
keep working the contractors,,,,small contractors need that kind of
work done,,,the big ones will already have the equipment,

otherwise, go directly to the building contractors remodeling, did
you find the contractors who specialize in remodeling buildings?

or, otherwise, I will shut up now,,,,maybe I am wrong about it if
you have tried,,,,
