Concrete for countertops is different than concrete for sidewalks. It is
2-2 1/2" thick verses 4" thick for sidewalk. It has smaller stones in it and
has reinforcement too.
I made my countertops out of concrete I guess because I did it myself and
the cost was $80.00 US. for the concrete the forms for the concrete the
stain the sealer and the urothene .As far as weight ,as some one else
mentioned ,they are no heavier than granite.
You also have a wide variety of colors to chose from.

I'm just wondering what genius says to him (or her) self,
"hey ! you know what, that concrete sidewalk outside my
office building would sure look purdy on my kitchen counter!"

is this the Starbucks yuppie, "hip" thing gone too far ??

how much weight is all that concrete exerting on the wood
cabinet - and the floor joists underneath it ?

is the typical 40 lb sq/ft live load rating of most homes
adequate to support the weight of all that concrete ? (and
all the other assorted appliances & people that would be in
the immediate area).
