Project description

The project seeks to develop proper methodology to use internal curing materials to improve the performance and to prolong the service life of concrete. Typical mix design of high-performance concrete (HPC) approved by Missouri Department of Transportation (MoDOT) will be used for the baseline mixture and will be modified with different types and contents of materials used for internal curing. The project will establish new mix design and curing recommendations of concrete made with internal curing materials and validate their performance through laboratory investigation and field demonstration. Quarterly Progress (Apr-Jun 2016): The Task Order was executed by MoDOT on July 8, 2016. Federal Regulations changed on June 30, 2016, which has caused a change in the F&A rate to go from 52.5% to 55%. This change will be documented via a letter that includes a new budget document. There will not be a formal supplemental agreement executed.
