Corrosion Resistance	Excellent (Highly resistant to rust, corrosion, and chemicals)	Low (Highly prone to rust and corrosion if not coated properly)	Good (Resistant to corrosion but can degrade over time)	Moderate (Resistant to corrosion but deteriorates over time)
Impact Resistance	High (Can withstand high impact forces without breaking)	High (Strong and impact-resistant)	Low (Prone to cracking and breaking under impact)	Moderate (Can crack under high impact forces)
Water Resistance	Excellent (Non-porous, does not absorb water)	Good (Does not absorb water, but can rust)	Moderate (Can absorb water over time)	Good (Water-resistant but porous, can absorb moisture)
UV Resistance	Excellent (Does not degrade under sunlight exposure)	Poor (Can degrade under prolonged sunlight exposure)	Poor (UV exposure can lead to brittleness and cracking)	Poor (UV exposure does not degrade material)
Fire Resistance	Moderate (Some grades are fire-resistant, but not all)	High (Highly fire-resistant, can withstand extreme heat)	Poor (Highly flammable, not suitable for fire-prone areas)	High (Fire-resistant due to cement-based composition)
Cost	Moderate to High (Higher initial cost but cost-effective in the long run)	High (Expensive material and costly maintenance)	Low (Cheaper than other materials)	Low (Cheaper than CI and FRP but requires frequent replacements)
Maintenance	Low (Requires minimal maintenance due to durability)	High (Prone to rust, requires regular maintenance and coating)	Moderate (Can degrade under harsh conditions)	High (Prone to cracks and requires regular maintenance)
