Precast Concrete Construction Details
Benefits of precast concrete construction
- Speed of construction is very fast
- Superior quality control
- Whole building can be precast-walls, floors, beams etc.
- Fast onsite construction
- Controlled conditions in the factory leads to superior quality
- As prestressing can be executed simply, it can decrease the size & number of the structural members
Application areas :-
- Concrete curtain walls
- As an external cladding (it may contain exposed aggregate)
- For structural walls
- With the power to precast in three dimensions, it facilitates precast panels to build up parts of mechanical systems
- Controlled conditions in the factory leads to superior quality
Slabs
- Density of 4", 6" & 8"
- Extent up to 25' - 0"
- Standard panel width = 4'-0"
- Standard designations = FS4 (FS = Flat slab; 4 = thickness of slab in inches)
Hollow core slab
- Density of 4", 6", 8", 10" and 12"
- Extent up to 40' - 0"
- Standard panel width = 4'-0"
- Standard designations = 4HC6 (4 = panel width in feet, HC = Hollow Core, 6 = slab
- density in inches)
Beams
Rectangular Beam (RB)
- Density of 4", 6", 8", 10" and 12"
- Extent up to 40' - 0"
- Standard panel width = 4'-0"
- Standard designations = 4HC6 (4 = panel width in feet, HC = Hollow Core, 6 = slab
- density in inches)
L and IT (inverted tee) beams (LB and IT)
- Generally utilized to provide to support slabs, walls, masonry and beams
- Standard beam width = 12"
- Depths of 20", 28", 36", 44", 52" and 60"
