Why this paper matters

Definitive state-of-the-art review establishing quantitative criteria for high-performance SHCC (HP-SHCC: fc ≥ 55 MPa, εtu ≥ 4%, strain energy ≥ 300 kJ/m³) and very-high-performance SHCC (VHP-SHCC: fc ≥ 100 MPa, εtu ≥ 8%, strain energy ≥ 800 kJ/m³), synthesizing 140+ international studies on matrix tailoring, fiber interfacial coatings, impact/blast resistance, and rebar-free structural systems.

Main contribution

Established performance boundaries differentiating conventional ECC, brittle UHPFRC, and ductile HP/VHP-SHCC.
Analyzed matrix optimization ($w/b = 0.13\text{--}0.25$, $s/b = 0.2\text{--}0.4$, ternary/quaternary SCMs) and PE fiber interfacial engineering.
Demonstrated that high-ductility high-strength SHCC delivers superior dynamic impact and blast resistance over UHPFRC.

Evidence summary

Taxonomy criteria:
HP-SHCC: $f_c \ge 55\text{ MPa}$, $\varepsilon_{tu} \ge 4.0\%$, strain energy $\ge 300\text{ kJ/m}^3$.
VHP-SHCC: $f_c \ge 100\text{ MPa}$, $\varepsilon_{tu} \ge 8.0\%$, strain energy $\ge 800\text{ kJ/m}^3$ (Section 1, page 1).
Comparison with UHPFRC: UHPFRC achieves higher compressive strength ($>150\text{ MPa}$) but limited strain capacity ($0.44\text{--}0.8\%$), whereas HP-SHCC provides 5–10x higher tensile ductility (Fig. 1, page 2).
Curing regime: Air curing is identified as superior to wet curing for preserving high tensile ductility in long-term exposure (Section 2.4, page 6).
