Concrete infused with fibreglass
Shown at a RIBA exhibition in 2004.
Imagine a building made of this?! The strength and exterior texture of concrete, but a lightness imbued by, well, light itself. At night, with lights on inside, shadowy projections of the inhabitants would be visible moving across the exterior of the building ...
The article suggests the real benefits are likely to be inside the building though. Could the ability for this new concrete to be as transparent, light, and airy as our ubiquitous glass mirrored buildings provide a richer set of textures for the built fabric of our cities?
