▎ 摘 要
NOVELTY - Formulation comprising three to six components, comprises 0-95 wt.% fine aggregate of limestone or siliceous of less than 4 mm particle size, 0-95 wt.% fine limestone or siliceous having grain size of less than 0.064 mm, 0-15 wt.% additive powder superplasticizer of polycarboxylic ether or its derivatives, 0-10 wt.% additive modulator type viscosity of cellulose ethers, biopolymers or their derivatives, 0-45 wt.% natural or synthetic graphite of high thermal conductivity, 0-20 wt.% graphene and/or carbon nanotubes (nano) having high thermal conductivity, and 0-95 wt.% a pozzolanic material. USE - The formulation is useful for producing structural concretes and mortars (claimed) which are useful in geothermal foundations of buildings. ADVANTAGE - The formulation provides structural concretes and mortars with thermal conductivity of 3.5 W/(Km), normal strength of 55 MPa, very dense and self-compacting (claimed), and improved mechanical strength. DETAILED DESCRIPTION - Formulation comprising three to six components, comprises 0-95 wt.% fine aggregate of limestone or siliceous of less than 4 mm particle size, 0-95 wt.% fine limestone or siliceous having grain size of less than 0.064 mm, 0-15 wt.% additive powder superplasticizer of polycarboxylic ether or its derivatives, 0-10 wt.% additive modulator type viscosity of cellulose ethers, biopolymers or their derivatives, 0-45 wt.% natural or synthetic graphite of high thermal conductivity, 0-20 wt.% graphene and/or carbon nanotubes (nano) having high thermal conductivity, and 0-95 wt.% a pozzolanic material comprising silica fume, pozzolan or fly ash. An INDEPENDENT CLAIM is also included for producing a greater or lesser thermal conductivity structural concrete or mortar comprising adding to structural concrete and mortar, modified proportions of the formulation or adding varying amount of the formulation to structural concrete and mortar.
