FIELD: building industry. SUBSTANCE: invention proposes the use of a mixture of technical lignosulfonates with aluminium production by-side product that is complex mineral salt as a complex addition. Complex addition is dried to powder-like state in fluidized layer at 78-82 C. Invention proposes different types of binding agents and filling agents and their combinations also. Composition is used for production of concrete and solution mixtures and articles based on thereof - concrete, ferroconcrete and structures of assembly and monolith building. Composition based on mineral binding agent, filling agent, water and complex addition ensures to improve physico-mechanical indices of concrete and ferroconcrete article and structures (strength, hardiness, waterproofness and others). EFFECT: improved quality of composition. 7 cl, 2 tbla |
