Abstract: It is disclosed the use of amorphous silica reagent produced from serpentine as pozzolane additive material, and more particularly a concrete mixture, such as high performance and ultra-high performance concrete, comprising a hydraulic binder; sand; aggregates, chemical admixture, mineral admixture as silica fume and an amorphous silica reagent (AmSR), wherein the AmSR is admixed for example with General Use Portland Cement and provides synergistic effect when combined with silica fume.

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.
