FIBRE-REINFORCED STRONG CONSTRUCTION MATERIALS AND COATINGS, CONTAINING INORGANIC BINDING AGENTS Russian patent published in 2015 - IPC C04B28/26 C04B41/50 C04B111/20 C04B111/27 

FIELD: chemistry.

SUBSTANCE: invention relates to a composition, including an acid-resistant inorganic binding agent and fibres. A composite construction material, containing at least one inorganic binding agent and a fibrous material, where the inorganic binding agent represents soluble glass, a fraction of the soluble glass content in the composite construction material constitutes 2-99 wt %, the fibrous material is present in the form of fibres in a bulk state, and/or in the form of threads, and/or in the form of a woven, and/or knitted, and/or mesh, and/or non-woven fibrous material, and/or canvas, and/or in the form of hollow fibres, and/or in the form of torn fibres, and/or in the form of cut fibres, and/or in the form of chopped fibres, and/or in the form of grinded fibres, the said material in addition to the said soluble glass contains the binding agent with latent hydraulic properties so that the application of the composition and/or the catalyst prevents Ca(OH)₂ formation, the said composition or catalyst contains at least one complexing agent. A moulded product, containing or consisting of the said composite materials. A coating, consisting of the said composite materials. The invention is developed in dependent formula claims.

EFFECT: increased chemical durability, water resistance, temperature resistance.
