State the term - Stresses from concrete to reinforcement
Stresses from concrete to reinforcement, or vice-versa, in reinforced concrete are transferred due to bond between concrete and steel reinforcement. Considering the type of construction in terms of when the prestressing tendons are stressed and how the prestressing force is transferred into the concrete, prestressed concrete may be classified into two types :
(a) Pre-tensioned concrete, and
(b) Post-tensioned concrete.
