Abstract
The world is passing through difficult and troubled times, and we live in a rapidly changing world. The construction industry is facing many challenges – global warming,climate change forces, and the capability to achieve sustainable development andeconomic progress without damaging our environment. The concrete industry inparticular faces further challenges. There is extensive evidence to show that concretematerials and concrete structures all over the world are deteriorating at a rapid rate, andthat we are unable to ensure their long-term durable service life performance. Toconfound this situation, we are also faced with an urgent need to regenerate ourinfrastructure systems if we are to eradicate poverty and provide a decent Quality of Lifefor all the peoples of the world. This report shows that the current emphasis on highstrength and very high strength, and the design philosophy of Durability through Strengthfor concrete materials and concrete structures is fundamentally flawed.
