    Well cement will wear down to the aggregate (the little rocks), which will wear at a different rate. Maybe they use a mix without it.

      Ya, no rocks. Next time I take my kid to the park, I can take a photo of the older slides. It wears are noticeable . It’s quite an amazing idea to use cement.
