Need of Innovations in Construction Materials
Infrastructure Decay Problems in Developed Countrie s- More Durable Materials should be Developed- Efficient and Effective Repair Materials are Requi red
Rapid Growth in Developing Countries (e.g., China)- Requirements on Material Durability, Sustainabilit y
as well as Construction Efficiency
Improvement of Living Quality- Functional Materials that are Self-Cleaning,
Sound-Proof, etc
