I read a post about mixing concrete in cold weather and was hoping some members could review the important stuff. I remember hearing that 26 degrees is a majic number for curing concrete and it should not go under that.
I am hoping to install granite edging on Friday and would love some tips and tricks. I spoke to a mason during the week and he said he puts anti-freeze in his concrete. Can this perevent bad things from happening below 26?
My plan of attack is to mix the concrete with anitfreeze when the temp is (barely) above freezing, cover it with plastic, hay, and one more layer of plastic for good measure, and them wait for the snow on Saturday.
I'm also hoping the ground gets a chance to thaw out before I pour the stuff. I am putting three inches of gravel below.
Any input would be appreciated!
