PROJECT NUMBER:  13-1

PROJECT TITLE: “Development of High Early-Strength Concrete for Accelerated Bridge Construction Closure Pour Connections”

PRINCIPAL INVESTIGATOR(S) & UNIVERSITY(S): Sergio F. Brena (BI) – University of Massachusetts Amherst, Scott A. Civjan (Co-PI) – University of Massachusetts Amherst

STATUS: Open

AGREEMENT TERM:   9/1/2014 – 4/2/2016

ANTICIPATED COMPLETION: 8/31/2016

A no cost extension is expected to be requested to accommodate the current coordination contract that NETC has with the University of Vermont.  The proposed project was for 24 months.

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

REPORTS/PAPERS PUBLISHED, PRESENTATIONS MADE RELATING TO THIS PROJECT FROM THE START OF THE PROJECT THROUGH MARCH 31, 2015:   None thus far.
