Porosity has been measured on a suite of selected drill cores from single cokes prepared in non-recovery and slot ovens. The cokes were selected because they have no aberrant ash chemistry. The size of the porosity dictated the techniques used: He-pycnometry and Petrographic Image Analysis (PIA). The cores were subsequently reacted in a CRI test. The objective was to replicate the familiar van der Velden CSR-CRI relationship, with the addition of porosity data. CSR can then be inferred from porosity data alone, and the observed spatial variation explained by geographical location in the oven. The mean pore size, pore size distribution and pore density are determined statistically and are measured by PIA.
