FIELD: building materials. SUBSTANCE: mastic has bitumen alloy with powder-like hydrolyzed lignin -lignobitumen instead of bitumen as binding agent. Emulsifying agent: claydite dust - waste of claydite granule roasting instead of highly dispersed natural clay. EFFECT: increased strength, heat resistance and hydroinsulating capability of bitumen hydrolyzed mastics. |
