[Energy and environmental research emphasizing low-rank coal]: Task 5. 8, Development of a coal by-product classification protocol for utilization. Topical report, January--September 1995

PDF Version Also Available for Download.

Description

The scope of work for this task was limited to the development of a general process to evaluate coal fly ash for use in applications beyond cement and concrete. Two coal fly ash samples were evaluated for appropriateness in structural fill as an example of how to use alternative classification protocol as ash use standards are developed for the industry. The goal of this project is to develop a classification system for fly ash based on parameters that relate to performance specification of engineering and construction applications. The new classification system will provide a means of evaluating the suitability of ... continued below

Description

The scope of work for this task was limited to the development of a general process to evaluate coal fly ash for use in applications beyond cement and concrete. Two coal fly ash samples were evaluated for appropriateness in structural fill as an example of how to use alternative classification protocol as ash use standards are developed for the industry. The goal of this project is to develop a classification system for fly ash based on parameters that relate to performance specification of engineering and construction applications. The new classification system will provide a means of evaluating the suitability of coal ash for use in certain products that currently have no reality-based standards or classifications. Recent work by the American Society for Testing and Materials (ASTM) Committee E50 on Pollution Prevention has proposed a standard practice for use of coal ash for structural fill applications. Energy & Environmental Research Center (EERC) coal ash researchers have worked on preparing this standard practice, and the development of criteria for the coal ash to be used in this application will facilitate the use of this standard once approved by ASTM. A preliminary flowchart for classification criteria was developed and is shown in figure 1.
