Modern day concrete floors are fully customizable with a variety of beautiful finishing options to choose from. Scope according to grit sizes shown below. The surface finish quality is specified as one of five classes.
Each class includes what aci 302 calls special considerations and suggested finishing techniques. In fact today s concrete floors come in a range of stains colors and textures. Position statements 1 slab protection by others 2 slip resistance of polished concrete 3 coordinating the concrete and polishing contractors subcontracts 4 separation of semirigid concrete floor joint fillers 5 effects of slab surface finish density on polished concrete. F numbers provide architects and contractors a method of determining the flatness and levelness of a concrete floor slab.
To set an industry standard that supports polishing contractors. Exposed aggregate finished concrete. The construction of exposed concrete finish is to have leveled concrete floor surface distribute aggregate evenly and keep air voids to as minimum as possible.
