13-1 Development of High Early-Strength Concrete for Accelerated Bridge Construction Closure Pour Connections

Project Objectives

To develop and validate concrete mixtures capable of developing high early strength without detrimentally affecting their long-term durability.  The mixtures are for use in projects using accelerated bridge construction methods.

Progress/Accomplishments Through March 31, 2015

  • Initiated the literature review by collecting and summarizing research reports and journal papers.
  • Reviewed ASTM/AASHTO materials testing standards that are applicable to the project.
  • Prepared a survey that was sent to New England State DOTs and precast/prestressed producer members of the PCI Northeast Bridge Technical Committee.
  • Met at the PCI Northeast Bridge Technical Committee to discuss project and seek feedback.
  • Executed a kickoff meeting with members of the NETC Project Technical Committee.
  • Compiled and analyzed responses to the survey that was sent to New England State DOTs and precast/prestressed producer members of the PCI Northeast Bridge Technical Committee, including previously used high-early strength concrete mix designs and specifications.
  • Began to prepare concrete mix design specifications based on the literature review and feedback from surveys.
  • Began a written summary of the literature review including main findings of relevant research reports, technical papers and survey
  • Tested preliminary concrete mix designs and compared test results using compressive strength tests on 4 by 8 in. cylinders and work-ability of each trial
  • Adjusted existing concrete mix design specifications based on preliminary test results; design specifications will continue to be modified throughout the duration of the
