Abstract

Construction wastes have become one of critical issues in lifecycle asset management, slowing down the path towards net zero. Accordingly, the contribution of recycled materials in building design and construction is needed. In such a context, recycled steel fibres (RSF) from waste tires have been considered as an alternative to the industrial steel fibres(ISF). This paper presents a comprehensive and critical review on RSF use relatively to fibre properties, as well as the mechanical properties of RSF reinforced concrete. Both at wet and hardened state comparative analyses between ISF and RSF to improve compressive strength, splitting strength and flexural strength is performed. Moreover, based on the data of global warming potentials and prices, investigates the contribution of RSF towards sustainable development and economy in comparison with ISF.
