Precast hollow floor units
These large precast reinforced concrete, hollow floor units are usually available in following dimension

Precast concrete floors are designed primarily to eliminate shuttering and wet concrete pouring processes that make the construction of an in situ cast reinforced floor a slow procedure.
The advantage of the completely precast floor is that it can be constructed rapidly and readily it provides a platform from which further work on the building can immediately go on.
A disadvantage is that it is less easy to provide a rigid connection between the precast unit and the supporting beams or wall. The precast beam or the precast rib and filler block construction must act together as a single unit to horizontal actions (wind, earthquake).
