The chemical and physical behaviour of matt waste (MW), a by-product which derives from purification processes of cullet from separated glass waste collection, has been studied as new component for cement based materials. Up to now, recycling for MW is not fully exploited. The aim of this research is to investigate the possible benefits of MW addition to cement systems. Investigations on paste samples cured in accelerated conditions were carried out with different analytical techniques (FT-IR, TGA, SEM, MIP) to investigate MW reactivity with portlandite and its effect on pastes microstructure. The results highlight pozzolan behaviour of MW at long curing time and a refinement of porosity leading to a compact microstructure.

Abstract

The chemical and physical behaviour of matt waste (MW), a by-product which derives from purification processes of cullet from separated glass waste collection, has been studied as new component for cement based materials. Up to now, recycling for MW is not fully exploited. The aim of this research is to investigate the possible benefits of MW addition to cement systems. Investigations on paste samples cured in accelerated conditions were carried out with different analytical techniques (FT-IR, TGA, SEM, MIP) to investigate MW reactivity with portlandite and its effect on pastes microstructure. The results highlight pozzolan behaviour of MW at long curing time and a refinement of porosity leading to a compact microstructure.
