MINI SESSION: Innovative Material Sources for Concrete Pavements
Tuesday, October 19, 2021 3:00 PM - 4:00 PM
Innovative material sources for concrete pavements.
(1) Demonstrate the use of innovative and non-traditional materials for incorporation into mixtures for use in concrete pavement structures;
(2) Describe the use of Recycled Concrete Aggregate in concrete pavements;
(3) Explain how ground glass can be used as a cementitious material;
(4) Describe the changing role of fly ash and other pozzolans in concrete mixtures.
This session has been approved by AIA and ICC for 1 PDH (0.1 CEU). Please note: You must attend the live session for the entire duration to receive credit. Mini Sessions will not be available on-demand.
Use of Ground Glass as a Cementitious Material
Presented By: Arezki Tagnit-Hamou
Affiliation: University of Sherbrooke
Description: Several types of ground glass can be used as a supplementary cementitious material in concrete, and recent research has demonstrated their effectiveness. This presentation describes some of the recent research and the development of a new standard specification on ground-glass pozzolan.
Recycled Concrete Aggregate
Presented By: Tara Cavalline
Affiliation: University of North Carolina At Charlotte
Description: This presentation will describe the use of recycled concrete aggregate for use in concrete pavements, including several case studies highlights.
New Directions for Fly Ash and Other Pozzolans
Presented By: Larry Sutter
Affiliation: Michigan Tech Transportation Institute
Description: With coal-fired power plants closing, fly ash supplies are becoming challenged in some markets. This talk will discuss trends in fly ash supply and quality and will discuss other materials that can be used in place of fly ash in concrete.
