The life expectancy of a concrete floor will far surpass that of most other flooring surfaces.
Therefore, the lifespan of polished surface (i.e. shiny look) directly related to 1). Material matrix structure: for marble - percent of calcite, for concrete - type of embedded aggregate and MPa, for terrazzo / agglomerates - epoxy component 2). Amount of traffic, type of traffic (dragging generator or stove over a polished floor is not a great idea) and maintenance program.
Above factors are not relevant to diamond polishing process applied.
