Abrégé

The present invention relates to a system for constructing a pavement on a soil, said system comprising a geosynthetic material and a chemical composition, said chemical composition comprising: a) one or more components selected from the group consisting of sodium chloride, potassium chloride, magnesium chloride, calcium chloride, strontium chloride, barium chloride and ammonium chloride, and b) aluminum chloride, and; c) one or more components selected from the group consisting of silica, zeolite and apatite. The invention moreover relates to a pavement construction comprising at least a soil (1), a geosynthetic material (5) applied on the soil (1), a base layer (6) applied on the geosynthetic material (5), and a top layer (9, 11, 12) comprising a soil composition, a cement, and a chemical composition, as well as to a method of constructing such a pavement.

Abrégé

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.
