The EU policy of reducing the emissions of combustion generated pollutants entails climate induced deterioration to become more important. Moreover, products applied to preserve outdoor built heritage and their preliminary performance tests often turn out to be improper. In such context, the paper reports the outcomes of the methodology adopted to assess the durability and efficiency of nano-based consolidating products utilized for the conservation of carbonate artworks, performing field exposure tests on Carrara marble model samples in different sites in the framework of the EC Project NANOMATCH. Surface properties and cohesion, extent and penetration of the conservative products and their interactions with marble substrates and environmental conditions are here examined after outdoor exposure for eleven months in four different European cities and compared with the features of undamaged and of untreated damaged specimens undergoing the same exposure settings.
欧盟减少燃烧生成污染物排放的政策使得气候引起的恶化变得更为重要。此外，应用于保护户外建筑遗产的产品及其初步性能测试往往结果并不理想。在此背景下，本文报告了用于评估纳米基加固产品在保护碳酸盐艺术品方面的耐用性和效率的方法学的结果，该方法学是在欧盟项目 NANOMATCH 的框架内，在不同地点对卡拉拉大理石模型样品进行了为期 11 个月的户外暴露试验。在四个不同的欧洲城市进行了 11 个月的户外暴露后，对表面性能和附着力、保护产品的渗透程度及其与大理石基质和环境条件的相互作用进行了研究，并与未经处理的受损标本以及经过相同暴露条件的未受损标本的特征进行了比较。
