Factors that may affect the results in the determination of the BET-specific surface area of hydrated Portland cement and related materials are analyzed on the basis of available experimental data. In addition to factors brought about by starting mix composition and curing conditions, the obtained result is also influenced by sample preparation, especially by the way free water is removed from the pore system. The consistently lower BETN2 values, as compared to BETH2O results, are brought about by the extremely restricted ability of nitrogen molecules to penetrate small pore entrances under conditions used in the measurement and to enter a part of the overall pore space.
