Abstract

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.

Abstract

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.

Abstract

A catalyst composition for pozzolan compositions, includes: a) one or more chlorides, selected from the group consisting of: sodium chloride, potassium chloride, magnesium chloride, calcium chloride, strontium chloride, barium chloride and/or ammonium chloride, preferably ammonium chloride; b) aluminum chloride, and c) one or more 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 magnesium oxide or calcium oxide, most preferably magnesium oxide. The use of the catalytic composition for addition to cement for oil well cementing, and for lowering the pH of cement, a method for obtaining a composition for reinforcing cement, a binder composition and a construction composition are also described.
