This review analyzes how various modification methods improve interface properties in rubberized concrete, suggesting solutions to enhance mechanical performance and durability.
The recycling of waste tires as aggregate in cement concrete offers an effective solution to environmental challenges by reducing waste and conserving natural resources. However, the weak interface between rubber aggregate and cement stone hinders the full utilization of waste tire rubber. This study analyzes over ten modification methods, both physical and chemical, aimed at improving the rubber-cement stone interface. It compares the effects of these techniques on interface properties, mechanical performance, and durability of rubber concrete. By addressing the current limitations, this research proposes solutions to overcome the bottleneck in the recycling and application of waste tire rubber, advancing the utilization of this resource and contributing to the reduction of "black pollution." Future research should prioritize developing more efficient interface modification technologies, optimizing fiber-rubber-concrete composite systems, and establishing unified engineering standards to promote the large-scale application of rubberized concrete.
