COMPOSITION FOR MANUFACTURE OF BUILDING MATERIALS Russian patent published in 2004 - IPC

FIELD: compositions on base of mineral binders, such as cement, lime, gypsum, or their mixtures; manufacture of building materials, corrugated asbestos board, plaster, finish coats and stucco molding.

SUBSTANCE: proposed composition contains mineral binder selected from group including cement, lime, gypsum or their mixtures and water; it additionally contains carbon clusters of fulleroid type at number of carbon atoms of 36 and more at the following relationship of components, mass-%: mineral binder, 33-77;carbon clusters of fulleroid type, 0.0001-2.0; the remainder being water. Polydispersed carbon nano-tubes may be used as carbon clusters of fulleroid type. Polyhedral multi-layer carbon nano-structures at interlayer distance of 0.34-0.36 nm and sizes of particles 0f 60-200 nm may be used as carbon clusters of fulleroid type. Mixture of poly-dispersed carbon nano-tubes and fullerene C₆₀ may be used as carbon clusters of fulleroid type. Composition may additionally contain technological additives in amount of 100-250 parts by mass per 1000 parts by mass of mineral binder.

EFFECT: enhanced physico-mechanical characteristics.
