APPLICATION OF RETARD-BONDED PRESTRESSED TECHNIQUE IN PROJECT OF LIHONG ECOLOGY HOMELAND

It is introduced the application of retard-bonded prestressed technique to high-level structure of large-span slabs of Lihong Ecology Homeland project,put forward the design method and construction craft of retard-bonded prestressed concrete plate,and pointed out that the matters needing attention in construction of retard-bonded prestressed concrete technique.According to the practice,it is concluded that the control over the curing time and pull-time of relief binder is the most critical issue in retard-bonded prestressed concrete construction process.Which can give a reference for retard-bonded prestressed concrete construction
