In September 1998, a site investigation assessing the durability performance of ternary blend concretes was initiated by an academic-government-industry consortium. Different concretes were cast in the field to assess durability performance in an outdoor exposure setting as well as with standard lab tests. Resistances to the following deterioration mechanisms were assessed: alkali-silica reactivity, chloride ion ingress, and deicer salt scaling. Compressive strength was also measured at various ages. This paper describes this project in detail and presents field observations and lab findings up to 2 years later.
