I could use some advice on Sakrete cement slab. When I make a slab, I
usually let it cure for several months (even a year) before using. However,
I need to use a slab that was just made about three weeks ago. I have been
washing it daily and buried it a few days ago under wet mulch. It will be
used on the 1st of July. My question is: Is there anyway I can lessen the
possible damage to trees planted on the slab or change the pH?
Thanks,
Julie
