Durability of Strain-Hardening Fibre-Reinforced Cement-Based Composites (SHCC)

Strain-Hardening Fibre-Reinforced Cement-Based Composites (SHCC) were named after their ability to resist increased tensile force after crack formation, over a significant tensile deformation range. The increased resistance is achieved through effective c
