<p>The present invention relates to a catalyst composition consisting of ammonium chloride, aluminum chloride, and magnesium oxide and uses thereof. Moreover, the invention relates to a method for obtaining a catalyst composition for reinforcing cement, comprising a combination of a) ammonium chloride and optionally one or more additional chlorides, selected from the group consisting of: sodium chloride, potassium chloride, magnesium chloride, calcium chloride, strontium chloride, and barium chloride; b) aluminum chloride, and c) magnesium oxide and optionallyone or more other metal oxides, preferably selected from the group consisting of: oxides from metals from Group II of the Periodic Table, oxides from metals from Group VIII B of the Periodic Table (e.g. iron oxide), more preferably oxides from metals from Group II of the Periodic Table, even more preferably calciumoxide; by firstly combining ammonium chloride, aluminum chloride, and magnesium oxide to form the catalytic composition and thenadding the remaining additives.</p> |
