RPC (Reactive Powder Concrete) is a kind of high performance concrete which has many excellent mechanical properties, and it has been applied in engineering practice. But, at present the research about RPC T-beam bridge is few at home and abroad, which has hindered the development of RPC bridge to some extent. Basing on the section of NC (normal concrete) T-beam bridge, the sectional optimization has been done, by means of the mechanical analysis about NC T-beam bridge of pre-stressed steel strand (the span is 40m), RPC T-beam bridge of pre-stressed steel strand and RPC T-beam bridge of pre-stressed CFRP (Carbon Fiber Reinforced Polymer) tendon, this paper reach the conclusion that the RPC T-beam bridge can greatly reduce the sectional size of T-beam bridge and reduce the weight by 23.7%. Therefore, considering the long-term perspective, the prospect of RPC T-beam bridge is good.
