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.

A composition for a ultra-high performance concrete comprising:
- cement particles;
- quartz sand with a diameter smaller than about 650 μm in a ratio between 0 and 1.4 of the cement content, glass sand with a mean diameter between about 250 μm and 400 μm in a ratio between 0 and 1.40 of the cement content, quartz powder with a diameter smaller than about 100 μm in a ratio between 0 and 0.40 of the cement content, reactive pozzolanic material in a ratio between 0.15 and 0.30 of the cement content, glass powder with a mean diameter between about 10 μm and 13 μm in a ratio between 0.10 and 0.90 of the cement content, fine glass powder with a mean diameter between about 1 μm and 3 μm in a ratio between 0 and 0.40 of the cement content, a superplasticizer in a ratio between 0.01 and 0.04 of the cement content, fibers, and wherein the composition has a water to binder ratio between 0.10 and 0.30.
