FIELD: chemistry. ^ SUBSTANCE: invention relates to construction materials, mainly to production of binding materials and can be particularly used in production of construction material. The ultrafine binding material is characterised by that it is obtained from a composition which contains the following, wt %: 8.33-31.91% aqueous solution of a hydroxide of an alkali metal 49.48-75.00, mineral material which contains amorphous silica - marl 25.00-50.52, where the weight ratio of the hydroxide of alkali metal in the aqueous solution is defined from the ratio to the weight of the amorphous silica in the range 1:(1-4). The hydroxide of the alkali metal used can be sodium hydroxide or potassium hydroxide. Sodium hydroxide obtained from a causticisation reaction of soda and slaked lime can be used. ^ EFFECT: high corrosion resistance of articles obtained using said binding material, strength properties and physical and mechanical properties of the binder, improved quality of the obtained material. ^ 3 cl, 4 ex, 5 tbl |
