Several factors were identified relative to the performance of EOT PCC. Each of these factors was considered in terms of freeze-thaw, shrinkage, chemical attack, abrasion resistance, fatigue life, volumetric expansion, practicality, and concrete costs. The assessment discusses material combinations, mixture designs, and construction practices on performance. A computer program using utility decision theory was applied in evaluating the parameters. Promising combinations of the above factors were determined based on the existing knowledge of material combinations used for EOT PCC, coupled with our understanding of the potentials of high performance concrete (HPC) for this type of application
