PS many more questions to follow. please be kind...
> The compressive strength of concrete is always based on 28 days of curing
> time. If you specify 3500 PSI concrete, it will take 28 days of curing to
> reach that strength. After 28 days, it will continue to get stronger.
> After 7 days of curing it will only have reached about 60% of its 28 day
> strength. If you were to install your tower before the 28 days has
elapsed,
> it is possible that the concrete could be weakened by the premature
stresses
> that the tower puts on it. This may or may not be visible by inspection.
> Do what the manufacturer says. Let the concrete cure for 28 days minimum,
> and be sure to keep it wet during the curing process. Cover it with
burlap
> or black plastic and don't let the surface dry out. In spite of all
> anecdotal evidence to the contrary, play it safe and do it right. It's
only
> 4 weeks.
