Concrete is sometimes pretensioned. This is usually performed offsite, at the manufacturer’s plant. Which of the following elements is the least likely to be pretensioned? Select one: a. Beam b. Double tee slab c. Girder d. Cast-in-place elevates slab in parking garage e. Single tee slab

option D.

Explanation:

The Correct answer is option D.

Pretensioned concrete is the advance method of concreting. This method is used for large construction.

In this method, Tendons are inserted in the steel cage before casting. The tendons are stressed with the help of jack.  

When the tendons are stressed then concreting is done. This process is used to increase the strength of the structure.

The load-bearing capacity of Pretensioned material is far greater than normal concrete material.

Cast-in-place elevates slab in the parking garage is the element that is least likely to be pre-tensioned.
