Design/methodology/approach: Low carbon steels were intercritically annealed at 740°C followed by water quenching to obtain dual-phase structures with 37 per cent volume fraction of martensite dispersed in ferrite matrix.

Originality/value: The results reported show that dual-phase steel can be a good candidate for reinforcement in concrete especially in aggressive and corrosive environments.
