Materials Used in Prestressed Concrete - Civil Snapshot

Steel and concrete are the basic materials of construction of prestressed concrete. Ordinary mild steel and deformed bars used in R.C.C. are not used in PSC (Prestressed concrete) because their yield strength is not very high. In the PSC, loss of prestress (about 20%) occurs due to many factors.
