Structural performance of steel-concrete sandwich beams with carbon nanofiber reinforcement [PDF]

open access: yes, 2019
Cementitious materials such as concrete are typically characterised as quasi-brittle with low tensile strength and low strain capacity, which hence affect the long-term durability of the structure.
