由于短碳纤维的p型导电性引起塞贝克效应，碳纤维增强混凝土可用于温度传感。通过测量6种掺加或不掺加碳纤维或矿物外加剂（粉煤灰、硅灰）的硅酸盐水泥基混凝土的热电功率，研究了碳纤维增强轻量化混凝土的感温能力和矿物外加剂对塞贝克效应的影响。结果表明，碳纤维轻量化混凝土具有与普通碳纤维混凝土相似的塞贝克效应，但掺加矿物外加剂使其塞贝克系数降低。掺有矿物外加剂的碳纤维增强轻量化混凝土可作为建筑物的热传感器。
Carbon fiber reinforced concrete can be used to sense temperature owing to the Seebeck effect caused by the p-type conductivity of short carbon fibers. Both the temperature sensing ability of the carbon fiber reinforced lightweight concrete and the influence of mineral admixtures on the Seebeck effect were investigated by measuring the thermo electric power of six Portland cement-based concretes with or without carbon fibers or mineral admixtures ( fly ash, silica fume). It was found that the carbon fiber reinforced lightweight concretes had a Seebeck effect similar to the carbon fiber reinforced normal concrete, but their Seebeck coefficients were decreased by mineral admixtures. Carbon fiber reinforced lightweight concrete with mineral admixtures can be used as a thermal sensor in buildings.
