The incremental and cumulative PSD of GGBS blended cement pastes from 3 days to 180 days are presented in Fig. 4, Fig. 5. The decreased peak number over time can be clearly observed in Fig. 4. The peak number of incremental PSD curves for GGBS blended composites can be roughly identified as 5 at 3 days, 3 at 7 and 90 days, and 2 at 180 days, which is similar with the FA blended composites reported in [17]. Note that the 5th PSD peak mainly exists at 3 days for sample with 40% GGBS content. From

Ground granulated blast-furnace slag (GGBS) is a massively produced waste in iron-making process. In present work, the pore size range of GGBS blended cementing composites is finely segmented to reveal the scale-dependent fractal nature of pore surface. Results indicate that structural complexity and irregularity of C-S-H gels can be improved by GGBS. It is proved that an increase in the pore surface area helps to improve the complexity (fractal dimension, Ds) of the pore wall. Linear growth of Ds with specific surface area exists in almost all...
