Impact mechanism of nano-silica on early age negative temperature damaged cementitious materials

Key Points

• Early age negative temperature damages cementitious materials, affecting their integrity and performance.
• Incorporating nano-silica improves hydration and mitigates damage, enhancing durability under low temperatures.
• Experimental data shows that samples with nano-silica exhibit better mechanical properties compared to those without.
• The findings suggest potential applications in improving construction materials subjected to harsh conditions.
