I hope this should help.

Thank you for your message. I currently do not have direct access to a specific paper containing critical state lines or critical state data points for pond ash, fly ash, or coal ash. However, I recommend reviewing the following relevant references, which are commonly cited in geotechnical and environmental engineering research related to ash behavior:

Thank you for your interest.

While I’ll gladly share any references I come across, I’d also like to mention that my recent article, accepted in Case Studies in Construction Materials (Q1), explores the behavior of Class C fly ash-based geopolymer mortars. It includes insights that may indirectly support critical state interpretations.

I’d be happy to share the accepted version if you’re interested.

Best regards,

Dr. Hasan A. H. Altawil
