Here´s a good reason to store rebar nets inside - Pretty sure that it won´t reinforce anything but the ice in the current state :laugh:

I wonder if they have thought of doing things like this on pourpose...there are massive ammouts of heat released from concrete when it is poured...be interested to see if this type of set-up would do anything with that heat from the inside...especially on larger pours such as dams.Originally posted by Munkholm View PostComment

just out of curiosity how does concrete release "massive amounts of heat" when it is poured?Originally posted by gdoherty0102 View PostI'm retired, if you don't like it, go around!Comment

It´s a chemical reaction

Right...the chemical reaction between the cement and water puts heat off. This is not typically and issue, but on larger pours like they had on the Hoover (then Boulder) Dam that was a major consideration on how they would deal with the massive ammounts of heat dispursed.Comment

Yep, I just read that they figured if they just poured the damn as one huge pour, it would take 125 years to cure. lol
So what did they do? They did it in squares. Inside of each of these "squares" they put metal piping that would allow river water, then refrigerated water to run through the center of the pour and disperse the heat. When they were done, the filled the pipes with grout.
Pretty slick, considering it was done in the 1930's. lolDanComment

when you mix something with something else it creates a chemical reaction. That doesn't mean that it produces heat. I can see where the curing process might produce heat but I've been standing in the middle of some pretty large floor slab pours and they didn't warm me up a bitOriginally posted by Munkholm View PostIt´s a chemical reaction

Now...I may be a little off on this, but I don't beleive so. Chemicial reactions cause a change in energy, this energy is usually dissipated as heat.
A large floor slab has a large area to dissipate the heat across, so could be un-noticable in one area.Comment

again, I was just curious and not trying to be argumentative. I worked as a concrete finisher for 4 years while in school and I never noticed that concrete would get warm while it was curing. Probably as you say, due to the small quantity involved. And, my major was not Chemistry obviouslyOriginally posted by gdoherty0102 View Post
