In this paper, thgh-performmance concrete (HPC) ihcorporated with expansive agent and hybrid fiber, i.e., steel fiber, polyvinyl alcohol fber (PVA fiber), and polypropy[ene fiber (PP tiber), was produced. The properties measured included shrinkage and water permeation of the concrete The effect of hybrid fibers and/or expansive agent on the shrinkage and water permeation properties was investigated. Test results indicated that the hybrid fiber of different types and sizes could reduce the size and amount of crack source at different scales; hybrid fibers combthed with expansive agent provided better enhancement for shrinkage resistance and impeccability of HPC than monoincorpomnon of hybrid fibers or expansive agent; the improvemem of the shrinkage resistance and the impermeability of tbe concrete resulted from the combined use of expansive agent and hybrid flbers, which was dependent on the amount of expansive agent, types and sizes of hybrid fibers, total volume fraction of fibers, proportions of hybrid fibers, and so on. The relevant mecbanisms were also discussed based on the analysis of the test results of pore structure of the concrete.
