Abstract
PurposeThe purpose of this paper is to assess the effect of rubber on the durability and corrosion resistance of steel‐reinforced concrete by measuring the permeability, water absorption, corrosion potential, linear polarization resistance and AC impedance during 150 days immersion in NaCl solution.Design/methodology/approachPermeability, water absorption, corrosion potential, linear polarization resistance and AC impedance during 150 days immersion in NaCl solution have been measured. It was observed that the water permeability of rubberized concrete decreased with the addition of rubber. Scanning electron microscopy micrographs were used to study the bulk of rubberized concrete and it was shown that the interfacial zones of cement/rubber had an important effect on water permeability. The corrosion behavior of this concrete was investigated in the chloride solution.FindingsIt was observed that optimum corrosion resistance was obtained with low rubber contents.Practical implicationsThe research results can be used for the fabrication of concrete modified with waste tire material.Originality/valueThe paper describes a method suitable for fabrication of concrete modified with tire waste, especially from an economic standpoint.
