Effects of particle size distribution (PSD) of ground granulated blastfurnace slag (GGBS) on some durability properties (as defined by intrinsic oxygen permeability, total porosity and pore size distribution) of slag cement mortars. The PSD of CCBS was represented by the parameters of Rosin-Rammler (R-R) distribution function, namely position parameter x, and slope n. The results showed that oxygen permeability and total porosity of the mortar mixes studied increased with increases in water-cement ratios whatever the age at which the specimens were tested and irrespective of percentage of slag in the mixes.
