【Abstract】 Fluorinated polymers were applied to sand stone heritage in order to increase its compressive strength and consolidation as well as to enhance its resistance to desegregation by water.Parameters such as penetration depth,water uptake,water vapor permeability,frizzing and thawing cycles,compressive strength and drilling resistance were investigated in order to better understand the consolidation effects of fluofinated polymers.The evaluation indicated that fluorinated polymers can play a significant role in the improvement of strength and water-resistance for sand stone.更多还原
