Effect of treatments on pore network of granites

The response of five granite stones (fresh or submitted to accelerated agin g treatments) to consolidation and hydrofugation treatments has been studie d. Changes in free porosity and capillary absorption coefficient (CAC) have been monitored. Statistical analysis of the data indicates an important ef fect of these treatments on the changes on these physical properties, leadi ng to different fluid-transport capabilities through the stone. Simultaneou s hydrofuging and consolidating treatments have a larger effect than any tr eatment applied separately.
