<p>Binder for use in a spraying cement concrete contains a mineral hydraulic binder with a short reaction time for the hydraulic reaction and its particles are (partly) coated with a combination of a hydrophobising agent and an alkali-free accelerator. Binder for use in a spraying cement concrete contains a mineral hydraulic binder, especially a low-sulphate binder, preferably Portland cement, Portland composite cement, blast furnace cement, iron Portland cement or alumina cement and optionally usual additives. The components are such that reaction time for the hydraulic reaction is short. The binder particles are (partly) coated with a combination of a hydrophobising agent and an alkali-free accelerator and also an additive with the water present from 0.5 to 6 wt. %. Independent claims are also included for (a) a method of producing the binder; (b) spraying concrete containing this binder; and (c) a method of producing the concrete.</p> |
