摘要：Steel Fiber Reinforced Self-stressing Concrete (SFRSSC for short) is a new type of high performance cementitious composite with self-expansive performance and high crack resistance. SFRSSC is actually a kind of expansive concrete which self-stresses, namely pre-compressive stresses, are induced by dint of some restrictions generally provided by steel bars and steel fibers to concrete expansion after hydration of expansive cement. As a result of chemical reaction, concrete achieved pre-stresses by itself different from mechanical pre-stressed concrete, so called steel fiber reinforced self-stressing concrete. In this paper the material experiments of 40 SFRSSC prisms are carried out to determine the rule of the self-expansive behavior. According to the theoretical model, a procedure how to determine the self-stress is supplied in order to supply references to the structural applications of steel fiber reinforced self-stressing concrete.
