However, do not make it too dry. You want the correct mix of water to concrete mix. Also, the concrete should attain a strength of 3000 psi minimum before putting any heavy traffic on it. In my experience, 3000 psi usually is attained at +/- 72 hours (3days) minimum. I break concrete cylinders for a living. If this is going to be your foundation, you want to make sure that it is strong enough to hold the tonnage and not crack.

Ask yourself this. Do you want a structure to go up fast or do you want a structure to last for a long time?
