The effect of alkali and Si/Al ratio on the development of mechanical properties of metakaolin-based geopolymers
TL;DR: In this article, the development of Young's modulus of geopolymers between 7 and 28 days was observed to be dependent on alkali, with the Youngs moduli of Na-specimens decreasing at low Si/Al ratio, but increasing at high Si /Al ratio.

Comparative study on the characteristics of fly ash and bottom ash geopolymers.
TL;DR: The results show that both fly ash and bottom ash can be utilized as source materials for the production of geopolymers and the moderate NaOH concentration of 10 M is found to be suitable and gives fly ashand bottom ash geopolymer mortars with compressive strengths of 35 and 18 MPa.
