What type of reinforcement used in prestressing concrete?
Is it either the standard reinforcement used in conventional RCC structure, or is there any particular type or category of reinforcement for prestressing?

Hi, In simple words, there are three major types of reinforcement used in prestressed concrete.

The prestressing steel used for prestressed concrete can take the form of
The types of prestressing steel are:

Difference between Reinforcing Steel and Prestressing Steel
Both R.C.C and Prestressed Concrete employs steel bars or wires in order to sustain tension. But both the types of concrete make use of different steel.
The steel used by R.C.C concrete can be:
The steel used in Prestressed Concrete are wires, strands, solid bars as mentioned above. Prestressed concrete uses high tensile strength steel that is manufactured by increasing the carbon content in steel compared to ordinary mild steel used in R.C.C.
In prestressed concrete, the steel used is tensioned or prestressed. This results in loss of prestress in a range of about 20%. The use of mild steel bars or HYSD bars bring a greater loss than this value. Hence, it is necessary to have high strength tensile bars for prestressed concrete.
