A Review On Comparative Performance And Interfacial Mechanisms Of Crumb Rubber In Ordinary Portland Cement And Alkali-activated Slag-based Concretes
The incorporation of crumb rubber (CR) from end-of-life tires into ordinary Portland cement (OPC) and alkali-activated slag (AAS) based concretes offers a sustainable approach to enhance functional performance. CR improves elasticity, impact resistance, and thermal insulation; However, its hydrophobic nature limits interfacial bonding, reducing strength and workability. Surface treatment strategies, including chemical and thermal treatments, effectively enhance CR matrix adhesion.
