ABSTRACT

Rubberized concrete, while possessing excellent toughness, ductility, crack resistance, and seismic resistance, experiences a significant decrease in mechanical properties due to the hydrophobic nature of rubber particles, resulting in distinct interfaces between the rubber particles and the surrounding mortar. Due to the ability of nanomaterials to promote cement hydration reactions, they play a filling and strengthening role in concrete, improving the performance of the interface transition zone and microstructure of the concrete. Additionally, nanomaterials can reduce the porosity of rubberized concrete and significantly enhance its compressive strength and ductility, making them of significant importance in the application of reinforced modified rubberized concrete. Based on this, a comprehensive analysis and summary were conducted on the mechanical properties, durability, and interface structure of nano-silica modified rubber concrete, discussing the modification mechanism by which nano-silica enhances its performance. This study provides theoretical and technical support for the application and promotion of nano-silica in improving the performance of rubber concrete.
