摘要：Grey bricks were produced manually and used as the major traditional building materials in ancient China. However, the characteristics of grey bricks make them vulnerable to water, salt and other environmental factors. Organosilicon materials have been tested as the effective protective agents for silicate based stones. In this study, we evaluated the effectiveness of different organosilicon materials on grey bricks by total and half immersions. The penetration depths, appearance alterations, water adsorptions, hydrophobic properties, porosities and compressive strengths were measured after the treatments. The samples were also experienced the salt solution immersion, freeze-thaw and UV aging tests to evaluate the durability of different preservation treatments. It is found that different characteristics of the organosilicon materials lead to different preservation performances, but it remains difficult to determine an appropriate material for the preservation of ancient architectures built with grey bricks, considering the consolidation performance, water resistance property and durability.
