07 Assessment
Advantages
- 90% reduction in plastic shrinkage cracking
- Enhanced fire resistance through spalling prevention
- Corrosion-free reinforcement system
- Improved impact and fatigue resistance
- Reduced maintenance requirements
- 50-100 year service life expectancy
- Improved workability during placement
- Enhanced durability in aggressive environments
Constraints
- Higher initial cost than plain concrete ($50-100/m³ premium)
- Requires careful mix design and quality control
- Potential fibre balling if not properly mixed
- Limited contribution to flexural strength compared to steel
- Surface finishing may require additional attention
- Lower elastic modulus than steel reinforcement
