Concrete Technology Break Through
In the pass 20 year, there is a huge progress in concrete technology,
One of the biggest breakthrough in 21st century is the invention of ultra-high performance concrete (UHPC)
at least 4-6 times stronger than normal concrete (in compression strength)
at least 100 times more durable than conventional concrete design
Longer service and design life
Lower Carbon footprint
