Dadic, R., P. C. Mullen,M. Schneebeli, R. E. Brandt, and S.

Figure 8. Specific surface area (SSA) from microcomputed tomography (micro-CT) versus porosity. Black
 circles are full samples, and gray circles are subsamples that were evaluated to analyze cracked and
 noncracked areas. The dashed line is the linear best fit between density and SSA for all samples with
 density > 650 kg m^–3
