Advantages:
1. Greater strength and durability than conventional concrete due to the compression placed on the concrete by the tendons.
2. Reduced cracking and improved resistance to weather and seismic activity.
3. Greater flexibility in design due to longer spans and thinner slabs.
4. Reduced ongoing maintenance costs due to longer service life.
5. Faster construction times due to prefabrication and reduced need for formwork.
Disadvantages:
1. Higher upfront costs due to the specialized design and construction techniques.
2. Increased complexity and potential for errors in design and construction.
3. Limited ability to modify the structure post-construction due to the permanence of the post-tensioning tendons.
4. Potential for tendon corrosion if proper maintenance is not performed.
5. Require highly skilled and trained personnel to design and construct post-tensioned concrete structures.
