(Architecture + Archaeological Conservation) Evaluation of Organosilicon Materials for Conservation of Ancient Grey Bricks

Log in to save this to your schedule and see who's attending!

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, such as ethyl silicate, organosiloxanes, and silicone resin, have been tested as the effective protective materials 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 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 conservation treatments. It is found that different characteristics of the organosilicon materials lead to different conservation performances, such as water repellence, consolidation effect and durability. But it remains difficult to determine an appropriate material for the conservation of ancient architecture built with grey bricks.
