  •  Does cement cure in 20 hrs? (3+ / 0-)
    Recommended by:

    No cement I have ever poured (as concrete: cement+ sand+gravel) for slab, formed, or used as  sustrate or adhesive for tile is ever completely cured in 20 hrs time.
    How is it possible 1000's of psi would not blow un-cured or contaminated cement product?
