The disposal of rubber tyres has become challenging; on the other hand, the utilization of rubber tyres is also increasing daily in society. The successful use of crumb rubber as an alternative aggregate and bentonite as a partial cement replacement in concrete composites has been well established through prior research. These materials have individually demonstrated their potential to enhance sustainability, improve concrete properties, and reduce environmental impact, paving the way for innovative construction solutions. The present research evaluated the combined effect of concrete composites made from crumb rubber as fine and coarse aggregate, whereas cement was substituted with bentonite. The mix proportions were determined using the variables bentonite substitution (0% to 5%) and crumb rubber substitution in both fine (25%) and coarse aggregate (10%). The experimental investigations were carried out to determine compaction factor, fresh density, compressive strength, split tensile strength, resistance against magnesium sulphate (MgSO4), resistance against sodium sulphate (Na2SO4), and resistance against sodium chloride (NaCl). Samples were cured in water, then in MgSO4, Na2SO4 and NaCl solutions. After cleaning and weighing, compressive tests were conducted. Furthermore, the interfacial transition zone (ITZ) was also evaluated for a set of specimens. The results show that decrement in the behaviour of concrete was observed upon the addition of CA-CR and FA-CR. The compressive strength ranges between 5.1MPa to 26MPa and tensile strength is also impacted by the increase of aggregate content. The addition of bentonite up to 5% enhances the performance of concrete. The possibility of concrete made out of bentonite and crumb rubber aggregate was confirmed through this investigation.
Keywords: ITZ, bentonite, crumb rubber, sustainable concrete, fresh properties, Magnesium sulphate (MgSO4)
