Approach:
- Mix fly ash with alkaline silicate solution and cure at moderate temperature to produce geoplymers
- Fabricate Al-fly ash composites by melting and casting, and powder consolidation followed by equal channel angular processing (ECAP)
- Develop process and performance models
Objective:
- Determine the feasibility of converting fly ash waste into valuable materials by utilizing fly ash as the precursor
Payoff:
