Post tension concrete slabs are a type of prestressed concrete, wherein high-strength steel cables or wires are used to apply tension to the concrete slab. This prestressing force helps to counteract the forces of compression that would otherwise act on the concrete. Post tension slabs are typically used in the construction of bridges, parking structures, high …
This concentration of equipment permits almost factory conditions of construction and correspondingly high quality. The fabrication area (fig. 8) includes the formwork, concrete mixing plant, a rail-mounted tower crane, storage areas for reinforcing and prestressing steel and the jacking equipment.
