Herzog de Meuron : the photo-concrete façade of the Fachhochschule Eberswalde's library, 1998
Beton Brut architecture: Architectural concrete left unfinished or roughly-finished after pouring and left exposed visually. The imprint of the wood or plywood forms used for pouring is usually present on

Concrete art: This shows a more delicate softer looking side to concrete.
Lightwieght concrete: I discovered innovative ways of making concrete lighter so it can therefore be used for other means.
''The Lightweight Concrete Company: Foam Lite Industries makes extremely lightweight concrete. Our concretes can be up to 88% lighter than traditional concretes. How? We use expanded polystyrene (similar to small Styrofoam ® balls) as aggregate in place of sand and stone.
Today, manufacturers, contractors, builders, artisans, and individuals use Foam Lite concretes for buildings, homes, walls, water features, architectural elements, statuary, theme structures, insulating infill for standard concrete block, and green build applications. New uses for Foam Lite concretes are being developed all time.''
Structural lightwieght concrete is mainly used to reduce the dead load of concrete. This then enables the structural designer to reduce the size of any load bearing elements such as columns.
LITRACON: Light transmitting concrete - brings translence to a traditionally opaque material.
I found this particularly interesting.
