Technology: The Surface of a Concrete Building ­Element Is a Reflection of the Formwork

No other building material is so versatile in its use and workability as concrete. It is economical; and as a result of the standards governing its manufacture and use in construction, it can be produced to a constant, reliable quality. Furthermore, because of its initially fluid state, it can be cast to any required shape, given the appropriate formwork. Where left in an exposed form, concrete can be an important design element, the expressive range of which may be extended through the use of coloured cements and pigments. Furthermore, the surface can be treated in a number of ways, from polishing to sandblasting and bush-hammering.
