Limestone Vs. Crushed Concrete
Limestone vs. Crushed Concrete. In its pure form, limestone differs significantly from crushed concrete in that the former constitutes a naturally formed rock found in marine environments and the other a manmade construction material. Limestone may appear in crushed concrete as a material found in the cement used to mix concrete.

Exposed Aggregate Concrete
In the case of concrete, that beauty is in the form of decorative aggregate, either natural or manufactured. The decorative process of exposing aggregate has been around since the early 1900s, well before pattern stamping, stenciling, and decorative overlays became trendy. But this method is far from being ready for retirement.
