So the other day I take the day off work to help my dad pour concrete.
Talking to the 'cement truck guy' who has been in the business for 40 years (and
a week away from retirement on that particular day...)
I'm asking these questions that have been bouncing around in my mind snince I
was a kid, but not having access to 'concrete truck guys', I never had the
opportunity before to get these questions answered.
So it's like, "What happens if the truck breaks down on the highway and it has a
few yards of concrete inside and the concrete dries?"
Turns out that they actually don't throw away the mixer--they send a peon in
there with a jackhammer.
But here's the interesting bit--if you get to the wet concrete before it hardens
and throw a bag of sugar in there and mix it up, you have days before the
concrete hardens.
A bag of sugar? I ask. Yep--a bag of sugar will keep yards of concrete soft for
a long time.
This I did not know. Then I started wondering about how this was discovered in
the first place. I know that concrete has been around since before Roman times,
but how would this conversation take place?
"Umm, we need a way to slow down the cure time of concrete!"
"Hey I know, let's throw some sugar in there and see what happens!"
I also heard that its about 120 years after date of pouring when concrete is at
it's strongest point.
I just thought of the sugar bit when Richard mentioned the salt and meat.
