ABSTRACT
Over the past several years there have been two threads of research within concrete material development, all providing beneficial information in their own right. The first of these developments has been that of ultra-high-performance concretes (UHPC). Designed with the intent of providing an alternative to steel construction and to concrete intensive applications, these UHPCs have been able to attain very high compressive and flexural strengths. These mixtures are typically characterized by very small, densely packed particles, intense cement requirements, and special curing regimes. Through creating a higher performing concrete, less concrete can be used overall, and by creating elements in a precast facility, on-site construction times can be reduced.
