Application of hazardous serpentine rocks’ extraction wastes in composites with glass waste and clay-sand mix to produce environmentally clean construction materials

•It was developed ceramics with 70 wt% of hazardous serpentinite extraction waste.•Flexural strength of new ceramics (57 MPa) is 14 time higher than norms demands (4 MPa).•Novel ceramics exhibit primarily glassy structures with some crystal inclusions.•Obtained results permit bonding of all hazardous volatile “fibrils” of serpentine.
