Asphalt Emulsion Fiber-Reinforced SCC

Enhanced Impact and Damping

Synergistic incorporation of asphalt emulsion with polypropylene or basalt fibers significantly enhances the impact toughness and damping capacity of self-compacting concrete, making it suitable for transportation infrastructures under dynamic loads.

Advantages

Significantly improved impact toughness

The network structure formed by asphalt emulsion and fibers bridges cracks and toughens, increasing the impact toughness index by up to 11.6%.

Excellent damping and vibration reduction

Asphalt emulsion alone increases damping ratio by about 21%; combined with fibers, damping ratio increases by 8–16% and loss factor by 8–21%.

Applications

• Transportation Infrastructure Concrete：Improves crack resistance and durability of pavements and bridges under impact loads.
• Seismic-Resistant Concrete Structures：Dissipates seismic energy through high damping, reducing structural vibration response.
• Impact-Resistant Composites：Fiber bridging and asphalt emulsion toughening synergistically improve impact resistance.
• Damping and Vibration-Reduction Materials：Provides high damping ratio and loss factor to effectively absorb vibration energy.
