Summary:The invention relates to a method for producing a cement mixture. The method comprises: i) producing a reactive glass mix from one or more raw materials; ii) mixing the reactive glass mix with at least a filler and an alkaline activator to obtain a cementitious mix, step i) comprising: a) providing one or more raw materials, mainly comprising secondary raw materials; b) carrying out heat treatment on the raw material to obtain a reactive glass mixture, and carrying out heat treatment until the heat quenching of the reactive glass mixture is ended; c) optionally calcining the raw material, the weight of the secondary raw material obtaining the reactive glass mix being at least half of the total mass of the glass mix; the cement mixture has a compressive strength of at least 30 MPa after hardening for 28 days, in step a) one or more corrective substances can be added to the raw materials, the alkaline activator is selected from at least one of Na2CO3, K2CO3, Na2SO4 and K2SO4 in combination with at least one of
