Reinforced Concrete vs Prestressed Concrete SkyCiv

Apr 01, 2021  Prestressed Concrete 1. What is prestressed concrete. Simply put, it is concrete formed under stress. Reinforcement bars are placed in a form and stressed by the stretching of the bars at each end, inducing tension in the bar. Concrete is poured into the form and all around the bars while they are still being stretched.
