EFFECT OF TREATMENTS ON PORE NETWORK OF GRANITES

The response of five granite stones (fresh or submitted to accelerated aging treatments) to consolidation and hydrofugation treatments has been studied. Changes in free porosity and capillary absorption coefficient (CAC) have been monitored. Statistical analysis of the data indicates an important effect of these treatments on the changes on these physical properties, leading lo different fluid-transport capabilities through the stone. Simultaneous hydrofuging and consolidating treatments have a larger effect than any treatment applied separately.
