Evaluating the influence of nano-SiO₂ on the fracture of self-compacting concrete using the size effect method

Key Points

• Fracture behavior is enhanced with the use of nano-sio₂, leading to stronger concrete structures.
• The specific influence of nano-sio₂ was evaluated using the size effect method, demonstrating significant improvements in mechanical properties.
• Assessment involved comprehensive tests on self-compacting concrete incorporating various nano-sio₂ concentrations to observe changes in fracture.
• Findings suggest that integrating nano-sio₂ can enhance fracture toughness, indicating its potential for use in construction materials.
