Its all dependent on your climate. If you live in a damp area the temperature lag in the concrete leads to condensation. In areas with lots of ground moisture it will wick through the concrete to the air. In a dry area the air removes the water so fast you would never see a wet surface. Around here, if you lay a piece of plastic sheet tightly over it you will see water under the plastic if there is no vapour barrier underneath. This matters most when something like a sill is on the floor because it can keep it permanently damp.
There are water proof cements available too.
The blue board helps stop condensation by helping the concrete stay at air temp instead of ground temp. It also helps stop wicking because it is also a vapour barrier.
