Precast concrete- camelwayponents can be- camelwaybined with other construction materials, particularly steel or cast-in-place concrete, to create a "hybrid" system. Examples include architectural precast concrete cladding supported on a structural steel or cast-in-place concrete frame as well as precast, prestressed double tees or
There are two main types of panel systems used for concrete walls: precast concrete and tilt-up concrete. Both types of panels are typically erected with a Tilt-up panels are site cast from ready-mixed concrete, usually formed on top of the floor slab, for minimal site disruption. Flat casting simplifies the concreting process
Depending on the location of manufacturing relative to the project site, precast may also contribute to local materials credits in some green building rating systems. Most concrete materials are locally sourced. Also, precast producers are located throughout North America, and it is- camelwaymon to source the panels from a

Precast concrete contributes to green building practices in significant ways. The low water-cement ratios possible with precast concrete -0.36 to 0.38- mean it can be extremely durable. The thermal mass of concrete allows shifting of heating and cooling loads in a structure to help reduce mechanical-system requirements.
Whether it's a mix of office, residential and retail or a parking super-structure designed for 5,000 vehicles, precast concrete offers a tremendous amount of design flexibility for architects and time-saving, budget-friendly benefits for contractors and developers.

better than buildings built with other structural systems (Wyllie 1989). Although the use of precast structural walls in seismic areas of the world has been proved a cost- effective way for lateral resistance of buildings, the very big majority of structures are constructed with cast in place reinforced concrete (RC). During the past
The precast systems were so-called solid precast systems (connection of precast elements by means of grouting, welding or bolting). These systems were used to build very uniform apartment buildings. There was not much room for flexibility because flexible molds for solid parts were not available. They were not invented
