Abstract:
The combination of short micro-fibers and continuous textile reinforcement in cementitious composites can
yield desirable mechanical properties with respect to structural strengthening against severe loading, such as impact
or blast. Besides the high tensile strength, high stiffness and considerable inelastic deformation capacity of such
composites, their constitutive nature and fresh-state properties enable their application as thin layers by lamination or
spraying without contributing substantially to the dead weight of the strengthened structure and without imposing the
usage of molds and adhesives. The paper at hand presents an exemplary hybrid-fiber reinforced composite, consisting
of high-strength strain-hardening cement-based composites (HS-SHCC) and carbon textile reinforcement. The textile
was investigated in two configurations: with and without additional coating for bond-strength enhancement. In this
way, the influence of yarn-SHCC bond properties on the cracking and fracture behavior of the composites was
emphasized.
