Building material mixture, useful e.g. for the production of magnesium oxide-cement, comprises powdered magnesium oxide, a salty, magnesium ion compound-containing aqueous mixing solution, and an aggregate

摘要

Building material mixture comprises a powdered magnesium oxide, a salty, at least one magnesium ion (Mg 2+) compound-containing aqueous mixing solution, and at least one aggregate, where the powdered magnesium oxide and the magnesium salt of the mixing solution provide the dissolved Mg 2+ions, and the water is introduced and a binder of the composition of magnesium oxide and magnesium salt is dissolved in water to produce the Mg 2+ions and water for the aggregate. Building material mixture comprises a powdered magnesium oxide, a salty, at least one magnesium ion (Mg 2+) compound-containing aqueous mixing solution, and at least one aggregate, where the powdered magnesium oxide and the magnesium salt of the mixing solution provide the dissolved Mg 2+ions, and the water is introduced and a binder of the composition of magnesium oxide and magnesium salt is dissolved in water to produce the Mg 2+ions and water for the aggregate, where in an existing ambient temperature between the powdered magnesium oxide fed to the aqueous mixing solution and the dissolved Mg 2+ions of the mixing solution before mixing of the powdered magnesium oxide and the mixing solution, a molar ratio of 2.5-3 is provided, where the aggregate is at least a hard rock particle, which is hardened in combination with the binder: magnesium oxide and magnesium salt in water dissolved for the production of Mg 2+ions and water for magnesium oxide-cement.
