Architectural Precast Concrete
 



 
Architectural precast concrete allows the architect to ˇ§designˇ¨ his own stone. A wide variety of colours is available through the use of pigments, cements and aggregates and many interesting textures are available, such as acid etching the surface to create a sandstone effect, and polishing.

The plasticity of the materials during manufacture makes it ideal for the creation of mouldings and complex shapes.

Architectural Finishes

A wide range of finishes is available for Redland Precastˇ¦s architectural products. Colours are created through the use of pigments and selected coarse and fine aggregates. The colour appearance can also be varied with the different textures available.

Textures are provided by chemical or physical treatment of the surface or by mould linings. The following textures are available:
 
acid-etching, where the panel surface is treated with dilute acid to expose the fine aggregate and create a sandstone effect;
 
bush-hammering, involving the percussive treatment of the panel to create a rugged, crystalline appearance;
 
polishing, to create an appearance similar to polished natural stone;
retarding, where a chemical retarding agent is placed in the mould allowing the concrete in the surface of the panel to remain liquid at demoulding. The slurry is then washed off to reveal the coarse aggregate;
sand-blasting, creating an effect similar to acid-etching;
off-form finish; and
combinations of the above to create special effects.
 
It is possible to include more than one texture in a single panel.

Architectural Mouldings

The plastic nature of concrete allows the designer to create complex decorative elements, from classical ornament to modern, geometric shapes. Such pieces are usually cast in timber moulds or in rubber moulds where undercut sculptural forms are required.
