FIELD: construction materials.
SUBSTANCE: invention relates to the industry of construction materials and can be used for making non-autoclave hardening structural heat-insulating concrete for various purposes. Disclosed complex nano-modifier for non-autoclave hardening aerated concrete based on graphene structures and lignosulphonates contains a reinforcing and structure-forming additive – an aqueous solution of graphene oxide and a plasticiser – sodium lignosulphonate. Content of components is 0.00011 wt.% of graphene oxide and 0.08989 wt.% of sodium lignosulphonate. Invention also relates to a mixture for non-autoclave hardening aerated concrete containing the disclosed complex nanomodifier.
EFFECT: invention increases compression and bending strength of aerated concrete, as well as reduces its water absorption and heat conductivity.
