[Greenbuilding] Passive solar home--concrete overlayre thermalmass

[KTOT (g)]

The house was designed with a 1.5 in. slab (and very similar houses have 
been successfully built with stained slabs by this same designer/architect). 
The concrete contractor wanted it increased to two inches. Are you 
suggesting the slab should be more or should be less than 2 in., since that 
appears to be a concern of yours?

Then lets talk about why you would need 2" of mass on a floor to begin with?
For me that is the real question.

And I think that nails the biggest problem in this thread -- not enough
information provided by the OP.

I haven't read all of the postings to this thread but in what I did read, I
didn't see anything about specifically what it is about the slab that (in
the OP's opinion ) justifies it being demolished and replaced at the
contractor (or sub-contractor's ?) expense.

It's entirely possible that the shortcomings (the nature of which is an
unknown at this point (to me anyway) are due to poor (or just plain bad)
design/specifications.

In order to make any sort of reasonable assessment of the situation (short
of a site visit) I think that one would need:

(1) cross section of the floor (ie including everything in the supporting
substrate .... if wood framed, that would mean joist size/spacing/span,
sub-floor material/thickness, separation membrane, concrete mix used,
primary & secondary reinforcement details, some idea of concrete
placing/finishing/curing process followed, control joint spacing

... blah,blah blah.

Without that info, we're just taking pot shots in the dark.
