Abstract: In order to solve the problem that graphene (G) is uniformly dispersed in cement slurry and its dosage is too high when it is functionalized into cement-based materials, a graphene (G-SD) with both high conductivity and water solubility was selected as a conductive filler. The effect of sodium lignosulfonate (MN) on the dispersion ability of G-SD in saturated calcium hydroxide solution (CH) used for simulated cement pore solution in the presence of polycarboxylate superplasticizer (PCE) and the effects of G-SD on the resistivity, electrothermal properties, snow melting and deciding, and thermoelectric properties of cement paste were investigated. The absorbance test shows that when the mass ratio of MN to G-SD is 3∶1, the dispersion of G-SD reaches the best. The electrical performance test shows that percolation threshold of graphene cement-based materials is 0.4%. What's more, good electrothermal performance are shown under the threshold, the temperature of cement paste specimen can be increased by 320℃ for 20 min with 30 V voltage, and 4 cm thick ice layer can be basically melted within25 min, so it possesses good potential for deicing and snow-melting. The thermoelectric properties shows that Seebeck coefficient of cement paste specimen is 154.4 μV/K when the content of G-SD is 0.1% by the cement mass. The above studies show that G-SD can endow cement-based materials with excellent electrical, thermal and thermoelectric functional properties at very low dosage.
