Two types of slag–lime pastes were prepared from granulated blast furnace slag and calcium hydroxide in a weight ratio of 80:20 and using initial water/solid (W/C) ratios of 0.25 and 0.4, respectively, to produce low and normal porosity pastes. After being hydrated for various lengths of time, the pastes were examined for surface area and pore structure using the nitrogen adsorption technique. The results of surface area, total pore volume and mean hydraulic radius measurements were related as far as possible to the chemical nature and physical state of the hydration products formed.
