Lightweight Concrete Roof Decks

Structural concrete composite deck a supported steel panel deck system filled with normal weight or structural lightweight concrete.

Lightweight concrete roof decks.

Lightweight roof pavers were invented to follow the natural slope of the roof and where an existing roof or new roof construction requires a lighter load. It does not contain any water absorbing expanded fillers and requires only one fourth the mix water of expanded aggregate insulating concretes. Not only does the deck acts as a permanent formwork to the concrete but also provides adequate shear bond with the concrete. Cast with 1 of concrete laminated to a 1 1 2 of expanded polystyrene foam these pavers have the look and feel of a full weight paver yet weigh in at roughly half the load.

The normal weight concrete employs standard aggregates i e. 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. Elastizell low density insulating concrete is a mixture of portland cement water and elastizell pre formed foam. However when a lightweight structural concrete lwsc roof deck is poured in place it uses significantly more water.

Cellucrete has established itself as the leader in the lightweight insulating concrete industry with a proven track record of high quality installations throughout the. 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. Hard rocks with a low water absorption rate and weighs approximately 2403 kg m 3 150 lb cf. An effective new and reroofing solution.

Composite lightweight concrete floors according to en 1994 1 1 2005 composite slab is composed of profiled steel decking with an in situ reinforced concrete topping. With standard structural concrete the aggregate used is sand and stone. Lightweight insulating concrete decks non structural low density lightweight insulating concrete lwic can be placed upon a variety of structural deck systems that have been designed to carry loads.

Beneath the roof cover structural concrete roof decks are commonly topside insulated using adhered insulation panels or cast in place lightweight insulating concrete. The end result of the structural lightweight mix is a deck that can be 20 25 lighter than standard structural concrete. Low density insulating concrete roof decks are monolithic composite systems cast over galvanized metal decks structural concrete wood decks or existing roof systems. Elastizell low density concrete roof decks.

Since 1985 cellucrete corp has been applying lightweight insulating concrete for roof decks structural concrete engineered fill applications and floor fill installations.
