Project detail
Roadmap/Focus area(s):   Livability
Project Description:   Mitigation of alkali-silica reaction (ASR) gels and rebar corrosion in concrete by the use of fiber reinforcement. Replacement of cement with fly ash with associated greenhouse gas reduction. Use of recycled concrete to replace virgin aggregate in concrete mixes.
Goals:   Service Life Enhancement and Reduction in Carbon Footprint of Highway Structures
Product Type:   Research report
Test Methodology:   Use of steel and polymer fibers to mitigate alkali-silica reaction (ASR) gel formation. Use of recycled concrete aggregate.
Expected Benefits:   Longer pavement life and reduced carbon footprint.
Deliverables: Name: Report
Product Type(s): Research report
Description: Summary report on how fibers, recycled concrete aggregate, and fly ash can be used to mitigate alkali-silica reaction (ASR) gel formation in concrete structures and reduce the carbon footprint of the concrete by replacing cement with fly ash.
