Tactility

'The interior of any concrete element is hidden behind a skin. This skin conceals the internal stresses that allow the concrete to serve as a support or span, and protects it against environmental influences. It is the supporting surface for countless functions and demarcates space. It conceals both monolithic masses and slender, decorative and daring forms. It provides for structural and plastic expression. It reveals the play of colour and light and confers decorative refinement on the concrete.
The skin is composed of closely agglomerated cement particles. This skin may also be removed to reveal the interior of the concrete. Numerous treatments exist.'
