Decking material

Auburndale, FL
This decking is from 1985 when the pool was installed. Does anyone know what it is (what type, besides concrete)? More importantly, if I can stain it a color?

My old house had flocrete, but after 5 years in the FL sun it was time to re-stain. I pressure washed it, used TSP, then re-stained without any issue. I would like to know if I can treat this decking in the same manner. thanks
