Nano-perlite-containing building thermal insulation concrete and preparation method thereof
The invention discloses nano-perlite-containing building thermal insulation concrete and a preparation method thereof. The nano-perlite-containing building thermal insulation concrete is prepared from nano-perlite, cement, stone, sand, silica fume, water and additives, wherein the nano-perlite is prepared by sucking aerogel in the inner cavity structure of expanded perlite serving as a carrier. The heat conductivity coefficient of the building thermal insulation concrete disclosed by the invention can achieve 0.25-0.60W/(m.K), and the compressive strength can reach 30-60MPa, thus meeting the strength requirement of structural concrete and achieving good fire resistance, durability, shock resistance and constructability; meanwhile, the building thermal insulation concrete disclosed by the invention further overcomes the technical problem that the aerogel is difficultly applied to concrete due to low own strength.
