Abstract
There is provided a Ultra-high performance glass concrete (UHPGC) including between 300 and 1000 kg/m3 of cement, between 0 and 1400 kg/m3 of glass sand (GS), between 0 and 300 kg/m3 of reactive pozzolanic material, between 150 and 900 kg/m3 of glass powder (GP), between 0 and 600 kg/m3 of fine glass powder (FGP), between 5 and 60 kg/m3 of superplasticizer, between 50 and 300 kg/m3 of fiber; and, between 130 and 275 kg/m3 of water, wherein the content of GP is of at least 3 wt % of the UHPGC, and/or the content of GS is of at least 19 wt % of the UHPGC and/or the content of FGP is of at least 0.5 wt % of the UHPGC.
