Uses of Prestressed Concrete

There are a huge number of uses:

• Railway Sleepers;

• Communications poles;

• Pre-tensioned precast “hollowcore” slabs;

• Pre-tensioned Precast Double T units – for very long spans (e.g., 16 m span for

car parks);

• Pre-tensioned precast inverted T beam for short-span bridges;

• Pre-tensioned precast PSC piles;

• Pre-tensioned precast portal frame units;

• Post-tensioned ribbed slab;

• In-situ balanced cantilever construction – post-tensioned PSC;

• This is “glued segmental” construction;

• Precast segments are joined by post-tensioning;

• PSC tank – precast segments post-tensioned together on site. Tendons around

circumference of tank;

• Barges;

• And many more.
