PLASTER BINDING Russian patent published in 2005 - IPC

FIELD: methods of production of composition plaster bindings.

SUBSTANCE: the invention is pertaining to methods of production of composition plaster bindings on the basis of a technical (high-strength) plaster, slag and milled unslaked lime, which combine a fast setting and solidification with a capability to solidify in humid conditions. The plaster binding on the basis of a technical plaster, slag and milled unslaked lime in the capacity of a slag contains an arenaceous ferrochrome slag at the following components ratio, in mass %: the technical plaster - 70-85, the arenaceous ferrochrome slag - 15-25, milled unslaked lime - 0-5. The technical effect - an accelerated solidification of the composition and increase of its water-resistance by 10-30 %, simplification of the process of a binding production, decreased capital input, reduced cost of binding, utilization of ferrochrome slag.

EFFECT: the invention ensures accelerated solidification of the plaster binding composition, increased its water-resistance, simplification of the binding production process, decreased capital input, reduced cost of binding production, utilization of ferrochrome slag.
