Revolutionary developments relating to novel materials for concrete production and to modifications and improvements in the behavior of traditional materials have been taking place in the past two decades. The 21st century will see the emergence of high-strength, high-performance concrete, particularly in the world's infrastructure of roads, buildings, and bridges. The future will see an increase in urbanization and improvements which will increase the demand for concrete. There will also be an increase in by-product wastes, such as fly ash. Some of these environmentally unfriendly by-products can be used in new concrete, given better control techniques. The 21st century will become the golden age of environmentally friendly supplementary cementing materials for high-performance concrete. This paper expands upon this future vision of concrete properties.
