The effect of the degree of hydration and amounts of granulated blast furnace slag on the surface properties of Portland cement pastes were studied. The results obtained showed that the specific surface area S BET (m 2 /g) and pore volume V p (cm 3 /g) decreased on increasing the degree of hydration. The addition of different amounts of granulated slag effected a decrease in S BET and V p to an extent proportional to the amount present. These results were attributed to a replacement of clinker by the amounts of slag added and the formation of hydration products.
