Lightweight Structural Concrete Roof Deck

The end result of the structural lightweight mix is a deck that can be 20 25 lighter than standard structural concrete.

Lightweight structural concrete roof deck.

As a result lightweight structural concrete inherently con tains much more water than normal weight structural concrete. Roof assembly installation can occur immediately following the installation of our roof deck panels. Structural panels concrete roof deck is an innovative technology designed to provide a structural roof sheathing without the need for thermal barriers pouring setting or curing which resolves the latent moisture issue commonly found in roofing with poured concrete. Structural concrete deck a cast in place concrete deck serves as an integral part of the structure and is designed to carry heavy loads normal weight concrete is typically used for cast in place construction.

Structural concrete composite deck a supported steel panel deck system filled with normal weight or structural lightweight concrete. With structural lightweight concrete a mix of shale slate slag and clay are used and with this mix the aggregate is fully saturated prior to mixing. The normal weight concrete employs standard aggregates i e. They are often however part of a building design when future above roof level floors are contemplated.

The steel deck panels are embossed in a manner which when filled with concrete allows the elements of the construction to respond to load as a single unit. With standard structural concrete the aggregate used is sand and stone. Lightweight structural concrete is used in roofing related appli cations for cast in place concrete roof decks using removable forms. Structural concrete composite decks are somewhat uncommon at the roof level.

Light a lighter weight solution than poured concrete that can reduce the use of steel in the overall structure. Hard rocks with a low water absorption rate and weighs approximately 2403 kg m 3 150 lb cf. Beneath the roof cover structural concrete roof decks are commonly topside insulated using adhered insulation panels or cast in place lightweight insulating concrete. Usg s structural panel concrete roof deck can be applied with mechanical fasteners to serve as a structural substrate for direct mechinically or adhesive applied roof systems.
