Freezing and Thawing Testing of Field and Lab Concretes with the Same Aggregates, Technical Summary.

摘要

The goal of this study was to determine whether the differences in aggregate gradations, material proportions, and cementitious materials between standard KTMR-22 concretes mixed in the lab and field concretes made with the same aggregates would result in significant differences in freeze-thaw durability as measured by KTMR-22. Sampling concrete as delivered to the job site for freezing and thawing evaluation would provide assurance that the KTMR-22 test results reflect the performance of the aggregate used in the pavement.
