FIELD: chemistry.

SUBSTANCE: preparation of a cement fortification composition comprising a combination of sodium chloride, potassium chloride, ammonium chloride, magnesium chloride, calcium chloride, aluminium chloride, silica, magnesium oxide, magnesium hydrogosphate, magnesium sulfate, sodium carbonate and cement, by combining first ammonium chloride, chloride aluminium and magnesium oxide to form a catalyst composition and then add the remaining components. The construction composition comprises: i) an ash in an amount of 90.0-99.9 wt % of the total weight of the construction composition, the ash being fly ash or an ash residue; ii) a catalyst composition in an amount of 0.1-10.0 wt %, consisting of: a) one or more chlorides selected from the group consisting of sodium chloride, potassium chloride, magnesium chloride, calcium chloride, strontium chloride, barium chloride And ammonium chloride; b) aluminium chloride; And c) one or more metal oxides selected from the group consisting of metal oxides of Group II of the Periodic Table, metal oxides of Group VIII B of the Periodic Table; And iii) a cement in an amount of 0.0-5.0 wt % of the total weight of the construction composition.

EFFECT: obtaining a composition for hardening cement having an increased reactivity.
