Concrete is a mixture of cement, sand, and rocks of various sizes. These ingredients tend to separate by size, so the surface of the slab is mainly cement, with the rock packed a significant distance below. In an exposed aggregate floor the surface of the concrete is heavily ground, removing enough of the slab to consistently expose the large rock in the slab. When it comes to polished concrete floors, exposed aggregate is often the most sought-after installation and by far the most difficult.
One of the most important factors for an exposed aggregate floor is the concrete mix. While any slab can be ground to aggregate, you only have true control of the final outcome on a freshly poured slab with a modified mix.
