Honeycombing in concrete can be formed due to the improper consolidation of concrete. If Concrete is not consolidate when it is placed inside of form work air voids could remain between the forms and the concrete creating honeycombing. Proper consolidation can be achieved by the use of vibrators.
You should wait a minimum of 28 days before you seal concrete. If you pour your concrete in summer, than a minimum of 14 days is acceptable. If you seal concrete any quicker, there is a chance moisture will be trapped inside.
Depending on what kind of sealer you use, the concrete should be completely dry and firm enough to walk on. However, I know of at least one concrete sealer (Concrete Treat) that can be applied immediately after the concrete has been placed -- with no wait at all for curing. Check out the products as you go and see what might work best for you. See the attached link.

Re-bar (reinforced bar) is the metal strengthening used inside pre-stressed (pre-made) or other concrete products. It is the brown spikes poking up through the concrete columns of concrete framed buildings or road bridges that you can see mid-construction.
The inside surface of forms are oiled to prevent the concrete from sticking to the formwork when it dries. This allows the formwork to be easily removed without damaging the concrete surface. Oil also helps in creating a smooth finish on the concrete.
Beetles live inside trees and underground. While they can also survive on concrete, they do not live in such places.
