Testing Old Concrete with a Hammer, aka "Sounding"

[@metallitech]

Makes me wonder; how long into the curing process does it take to get that sound of good concrete? Does it have to cure for three months or is it ready to do that after just three days?

You can find me on Google, but I'm not licensed outside of Calif. Depending on where you are I can't offer specific consultation.
