| Abstract: |
Coarse aggregate activated powder concrete (CA-RPC) is a new modified material for the large- scale application of existing ultra-high-performance concrete (UHPC), which can improve the technical difficulties of existing materials such as harsh materials selection, high construction viscosity, large self-shrinkage, etc., and has the characteristics of ultra-high strength, low viscosity, low shrinkage, high toughness and high elastic modulus. Nanjing Lvdu Road bridge over New QinHuai River innovatively introduced coarse aggregate activated powder concrete and formed a new composite continuous beam bridge system with steel box. Through comparative analysis with the steel box- conventional concrete composite continuous girder bridge, prestressed concrete continuous girder bridge and other structural systems, the advantages of the new structural system such as large span lightweight, prefabricated assembly, and ecological environmental protection are expounded. |
