GRC can be shaped into almost any thinkable form to accommodate the architectural needs of a project. Many finishes can be achieved by adding iron dioxides to the slurry, exposing aggregate after casting, and by applying matrices to the mould. These qualities - together with the lightweight nature of GRC and its sustainability and durability characteristics - drives the large increase in popularity of the material, with both architects and builders (see Figure 1). Today, a range of fixing systems exists for GRC, with almost all of them allowing for hidden fixing. However, it is difficult for designers and installers to decide which fixing system to use for a project. A stud-frame construction can prove to be a superior option to other solutions.
