If you can bear to wait, covering the slab to hold in the moisture can substantially increase its strength. The industry standard is 28 days, but at least a week can make a huge difference.

What do you recommend covering it with DavidS? Tarp? Black plastic?

[david s]

Either of those should be fine. Ideally the whole thing is best sealed, but it may not be practical to seal up the underside, so just covering the top surface will stop sun and wind from drying it out.
