Civil Project On Pre stressed Concrete Technology
This is a Civil Project On Pre stressed Concrete Technology and Pre-stressing can be accomplished in three ways: pre-tensioned concrete, and bonded or unbounded post-tensioned concrete. You can use this report for your reference and study.Pre-tensioned concrete is cast around already tensioned tendons. This method produces a good bond between the tendon and concrete, which both protects the tendon from corrosion and allows for direct transfer of tension. You can also Subscribe to FINAL YEAR PROJECT'S by Email for more such Projects and Seminar.
The cured concrete adheres and bonds to the bars and when the tension is released it is transferred to the concrete as compression by static friction. However, it requires stout anchoring points between which the tendon is to be stretched and the tendons are usually in a straight line. Thus, most pretensioned concrete elements are prefabricated in a factory and must be transported to the construction site, which limits their size.
