In the two papers listed above, the conversion of the Seebeck coefficient (relative to copper) to the absolute thermoelectric power was done by using the wrong sign of the absolute thermoelectric power of copper (2.34 μV/°C). The corrected tables are shown below for both papers. The correction means that plain cement paste is slightly p-type rather than slightly n-type. In addition, it means that cement pastes with carbon fibers are more p-type and those with steel fibers are less n-type than reported. Note in Table III of Paper 2 that all cement pastes are p-type except for paste (ii). Note in Table IV of Paper 2 that all cement junctions are pn-junctions (rather than some being nn+-junctions).
