I understand how nails obtain their pullout resistance in fibrous materials like wood, but I see workers driving nails through wood into concrete. How does the cement prevent pullout?

Keep in mind that a correct installation of nails should not hold things in the direction in which the nail is pulled out, or at least not directly.
In most cases, you want your nails to hold two surfaces tightly together and avoid any sliding movement. The medium is not critical in that case, as long and the nail stays in place.
