Interesting.

Interesting if it works.

Is it good for wall building? ;-) Oops, buy American, and this new concrete additive is from the Dutch.

Is this just theoretical? I mean: I’d like to see something concrete.

I personally have urinated on enough miles of WV roads to carry me to the Moon.

A month or so ago I visited Hoover Dam. There was so much concrete poured into that thing that it will be another four or five hundred years before it's completely cured throughout.

Kind of a weird feeling to know that one is driving over a massive mound of wet cement...

I see a movie about this stuff on the SciFi channel in two years.

“Excuse me, but will this ice melt hurt my concrete?”

“This ice melt? No. Look, it even says so on the package.”

Next Spring.....

“Look at these photos! That ice melt you sold me destroyed our concrete!”

“That? That’s just normal wear and tear.. Concrete always melts like that when it gets too hot out. Put some shade over it next time.”

This is definitely not so!

Only concrete that is subject to tensile stress can crack.

Romans used pumice, volcanic dust, in some of their concrete formulations and where they did it has held up much better.

Concrete is very interesting I learned in a book titled STUFF MATTERS, which goes into interesting details about concrete, stainless steel and other substances. Not only does he discuss this self-healing concrete, he also describes concrete that combats air pollution and self-cleans.

Would galvanized re-bar be better? How much more would it cost?
