Title: High-volume fly ash utilization projects in the United States and Canada. Final report

Technical Report ·
OSTI ID:6074634

The purpose of this report is to document existing high-volume applications of fly ash. Examples of high-volume projects are: backfills, embankments, fills, landfill cover, pavement base course, soil amendment, subgrade stabilization, grouts and hydraulic fills. Information was solicited from electric utilities, state highway agencies, ash marketers, engineering firms and other organizations in the United States and Canada. Over 270 separate projects that used fly ash in high-volume applications were identified. Class F fly ash was used in 172 projects, and Class C fly ash was used in 108 projects. The most frequent high-volume use of Class F fly ash was for fills, embankments and pavement base courses. These projects are primarily located in the north central and mid-Atlantic states. The most frequent use of Class C fly ash was for subgrade stabilization. Most of these projects are located in the midwestern and southwestern United States. The existence of many different applications of fly ash documented during this project demonstrates that fly ash is a practical high-volume construction material.
