Glass waste versus sand as aggregates: The characteristics of the evolving geopolymer binders

Glass waste has been widely explored in geopolymer technology as a precursor blended with other pozzolanic materials or as a source for synthesizing alkali activators. In room temperature curing (which is desirable in concrete manufacturing), glass waste is not considered reactive. This is because the major silica content of glass is very resistant to dissolution at low temperatures. Therefore, in usual concrete manufacturing practices, glass...
