Abstract

"Solo Estabilizado para Dissipação Térmica". Trata-se de uma mistura usada para recobrimento de linhas de transmissão de energia elétrica por cabos subterrâneos. A mistura tem características geomecânicas que lhe conferem baixa resistividade térmica, da ordem de 0,50°C.m/W, quando compactada na umidade ótima. Tal mistura é composta por solo de gnaisse argilo-areno pouco siltoso misturado com 25% de caulim, saturado com íons polivalentes Ca^ ++^ ou Mg^ ++^ a 4% (40 g de CaCO~ 3~ ou MgCO~ 3~/litro de água). O Solo Estabilizado para Dissipação Térmica quando secado, atingindo umidade da ordem de 0,5%, fornece resistividade térmica menor que 1,0°C.m/W. Para umidades inferiores a 0,5% são obtidos valores de resistividade térmica entre 1,0 a 1,1°C.m/W. Variações no percentual dos materiais componentes do Solo Estabilizado para Dissipação Térmica, forneceram baixa resistividade térmica (da ordem de 0,42°C.m/W) para compactação em torno da umidade ótima. Tal resistividade térmica foi obtida usando-se caulim bruto, contendo aproximadamente 60% de caulinita pura, saturado com íons polivalentes de Ca^ ++^ ou Mg^ ++^ a 4% (40 g de CaCO~ 3~ ou MgCO~ 3~/litro de água)."Stabilized Soil for Thermal Dissipation". It is a mixture used to cover electrical energy transmission lines by underground cables. The mixture has geomechanical characteristics that give it low thermal resistivity, in the order of 0.50 ° C.m / W, when compacted in the optimum humidity. Such mixture is composed of low-silt clay-arene gneiss soil mixed with 25% kaolin, saturated with 4% Ca ^ ++ ^ or 4% Mg ^ ++ ^ ions (40 g of CaCO ~ 3 ~ or MgCO ~ 3 ~ / liter of water). The Soil Stabilized for Thermal Dissipation when dried, reaching humidity of the order of 0.5%, provides thermal resistivity below 1.0 ° C.m / W. For humidity below 0.5%, thermal resistivity values between 1.0 to 1.1 ° C.m / W are obtained. Variations in the percentage of the component materials of the Soil Stabilized for Thermal Dissipation, provided low thermal resistivity (in the order of 0.42 ° C.m / W) for compaction around the optimum humidity. Such thermal resistivity was obtained using crude kaolin, containing approximately 60% pure kaolinite, saturated with polyvalent ions of Ca ^ ++ ^ or 4% Mg ^ ++ ^ (40 g of CaCO ~ 3 ~ or MgCO ~ 3 ~ / liter of water).
