Aquatic environments can be severely harsh, so structures need suitable materials to endure them. Among the promising for aquatic are cementitious composites; however, their ability withstand degrading should evaluated. This study aims evaluate composite's mechanical and fracture behavior with seven mix designs in three submerged fresh saltwater exposed a simulated offshore tidal-splash regime. Environmental exposure durations were chosen as 28, 90, 365 days. Cementitious composites developed glass, PVA, PP fibers. The results show different behaviors, from fully brittle (without fiber) strain-hardening (made of PVA fibers). In splash zone environment, up 25% strength degradation is seen most severe conditions. parameters, indexes reduced more severely. failure patterns investigated, some SEM photos presented, statistical evaluations (including trends correlations) presented.
