New Silica Fume from Recycled Glass
Based on its high content of amorphous silica (SiO2), waste glass represents a good material for reclamation as glass nanoparticles (“glass fume”). When mixed into a cement paste, glass fume offer nucleation sites for portlandite and has both pozzolanic and filler behaviors. When adequately dispersed, glass fume increases slump of the cement pastes and mechanical properties of mortars. Moreover, it has been tested in high performance concrete (water-to-binder ratio (W/B) of 0.35). The evolutions of the compressive strength and of the permeability of the glass fume concrete are comparable of those of a high performance concrete mixed using silica fume.
