This is Photos of the Geelong Westfield car park. It uses a suspended concrete slab as the floor/ceiling of the first and second level car parks. This concrete slab is supported by Bondek. An interesting not is the use of uneven mixture used to cover the concrete beams. Shown in the photo below where the cladding has crumbled off revealing the concrete beam this is used to make the beams more fire resistant
Thank you to Liesa Nunn for her information that the cladding is usually made out of lightweight vermiculite and gypsum or cement.

Did you know that the covering of the beams is actually to fire protect them? It is a material used to protect steel from fire damage, and is usually a mixture of lightweight vermiculite and gypsum or cement.
