About this technology
Overview
Stennis Space Center engineers are always on the lookout for materials that can hold up better in the inferno of a rocket test. A Louisiana Tech University team had a good candidate: geopolymer concrete made with fly ash left over after burning coal. Testing under a dual-use cooperative agreement confirmed the material_s strong resistance to heat and corrosion, prompting the Louisiana Tech team to start Ruston, Louisiana-based Alchemy Geopolymer Solutions LLC, to help turn waste ash into concrete across the country.
