The specific surface area of the cement (area per unit mass) can be calculated from the particle size distribution parameters. The greater the slope, the narrower is the distribution. For equal specific surface area, cements with a narrower distribution have a smaller position parameter x' and thus a higher proportion of the fine particles.
