Architectural Visualization: Concrete - Part I - Analysis

Concrete comes in many forms, and I thought it might be time I finally make a detailed study into the different types of concrete.

Concrete Colors

The above pictures were found at, http://www.wfdecor.com/gallery/concrete-countertop.html#. Concrete can be dyed with every possible color.

Grit Levels

Little did I know, 
concrete is not considered polished before 400 grit, and it is normally finished to either the 800, 1500, or 3000 grit level.
So a little more research on concrete grit level yields this site, http://www.yankeefiber.com/polishedconcrete.php.

Grit Level 1500 and untreated

Brushed Concrete
And lastly, in the opposite direction of polished concrete, there are brushed concrete,

Aggregate Concrete
Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories-fine and coarse. Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a 3/8-inch (9.5-mm) sieve. Coarse aggregates are any particles greater than 0.19 inch (4.75 mm), but generally range between 3/8 and 1.5 inches (9.5 mm to 37.5 mm) in diameter. Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder.
