A composite steel deck combines the tensile strength of steel with the compressive strength of concrete to improve design efficiency and reduce the material necessary to cover a given area. Additionally, composite steel decks supported by composite steel joists can span greater distances between supporting elements and have reduced live load ...
Compared to other lightweight concretes, lightweight ECC has superior ductility. Applications include floating homes, barges, and canoes. ‘Self compacting concrete’ refers to a concrete that can flow under its own weight. For instance, a self-compacting material would be able to fill a mold containing elaborate pre-positioned steel ...
In a typical casting procedure, a decking of formwork is constructed out of metal or wood. This provides temporary support for the voids and the curing concrete. After the decking is constructed, reinforcing mesh is installed to support the voids. Alternatively, the voids and mesh may be supplied as a prefabricated module.
The CJ-Series Joists are capable of supporting larger floor or roof loadings due to the attachment of the concrete slab to the top chord of the composite joist. Shear connection between the concrete slab and steel joist is typically made by the welding of shear studs through the steel deck to the underlying CJ-Series Composite Steel Joist. [2]
Vacuum concrete, made by using steam to produce a vacuum inside a concrete mixing truck to release air bubbles inside the concrete, is being researched. The idea is that the steam displaces the air normally over the concrete. When the steam condenses into water it will create a low pressure over the concrete that will pull air from the concrete.
The Filigree Wideslab method is a process for construction of concrete floor decks from two interconnected concrete placements, one precast in a factory, and the other done in the field. The method was developed during the late 1960s by Harry H. Wise as a more efficient and economic construction process than conventional cast-in-place technologies.
Autoclaved aerated concrete (AAC) is a lightweight, precast, cellular concrete building material. Developed initially in the mid-1920s, it has expanded into widespread use. Developed initially in the mid-1920s, it has expanded into widespread use.
Expanded polystyrene (EPS) concrete (also known as EPScrete, EPS concrete or lightweight concrete) is a form of concrete known for its light weight made from cement and EPS (Expanded Polystyrene). It is a popular material for use in environmentally "green" homes.
