Beschreibung
Zusammenfassung:	FIELD: building industry. SUBSTANCE: invention relates to building composition based on mineral binding agent, filling agent, water and complex addition. Enzyme preparation - alkaline protease at pH = 9-12 is used as a modifying agent at the following ratio of components in mixture, wt.-%: aqueous solution of technical lignosulfonates, 95-97; alkaline protease at pH 9-12, 5-3. Fraction of molecular mass isolated from the indicated mixture and dried in fluidized layer at 78-82 C is used as an addition in composition. Invention proposes different types of binding agents and filling agents and their combination also. Composition can be used for production of concrete and solution mixture and articles based on ferroconcrete and structures for assembly and monolith building. EFFECT: improved physico-mechanical indices (strength, hardiness, waterproofness and others). 7 cl, 2 tbl
