» University of Texas-Austin research: Evaluating the Performance of Alternative Supplementary Cementing Material in Concrete. Done of behalf of the Texas DOT, the research evaluated the performance of eight commercially available natural SCMs as potential replacements for Class F fly ash in concrete formulations.

» The University of Utah Phase 1 Research Study. Quantified the performance of pumice as an effective pozzolan for improving concrete by mitigating common concrete ills and improving overall density and strength.

» The University of Utah Phase 2 Research Study. Focus was to further understand and quantify the dramatic effect pumice-blended cement had on mitigating the alkali-silica reaction, even in the presence of the most reactive aggregate.
