Discussion of "Geopolymers Based on Recycled Glass Powder for Soil Stabilization" Jair de Jesús Arrieta Baldovino; Ronaldo dos Santos Izzo; Juliana Lundgren Rose; Mônica Angélica Avanci.

Discussers offered comments to enhance results analysis. An alternative evaluation was proposed using the η/B_iv index, where the B_iv parameter, named as volumetric binder content, is expressed as a percentage of cementitious binder, which means for this work the sum of volumetric cement content plus volumetric glass powder content. Finally, background literature was suggested. [ABSTRACT FROM AUTHOR]
