FIELD: construction; chemistry.
SUBSTANCE: group of inventions relates to a long-term stabilized aqueous composition of an initiator for initiating setting and hardening aluminous cement compositions, to a method of producing said long-term stabilized aqueous composition of an initiator, as well as to use of said composition in system for chemical fastening of fasteners in mineral surfaces. Initiator composition contains at least one activator component, at least one accelerator component, at least one setting retarder, at least one mineral filler, at least one thickening agent and water. At least one activator component contains at least one sodium or lithium salt selected from a group consisting of hydroxides, chlorides, sulphates, phosphates, monohydrogen phosphates, dihydrophosphates, nitrates and mixtures thereof. At least one accelerator component contains at least one salt of sodium or lithium, selected from a group consisting of hydroxides, chlorides, sulphates, phosphates, monohydrogen phosphates, dihydrophosphates, nitrates, carbonates and mixtures thereof. At least one setting retarder is selected from a group consisting of citric acid, tartaric acid, lactic acid, salicylic acid, gluconic acid and mixtures thereof. At least one mineral filler is selected from a group consisting of limestone fillers, corundum, dolomite, alkali-resistant glass, crushed stone, gravel, pebbles and mixtures thereof.
EFFECT: technical result is improved mechanical characteristics of fastening fasteners, improved stability of storage composition.
