22.10.2024 Alkylalkoxysilanes and -siloxanes for water repellent treatments: New ways for investigations for the understanding of complex reactions Back Tools Bookmark Share The pore network of plaster plays a major role in the rating of its durability and performance limits, especially when liquid and vapor water transport is involved. Due to the presence of water in the plaster, many degradation processes such as salt crystallization, dissolution and leching or biological decomposition were accelerated. To prevent these deterioration processes, hydrophobic additives are added to the plaster. However, there are also some products with hydrophilic properties that can provide comparable performance. In our performance study we present different plaster systems with different pore network and various ideas regarding moisture transport. We used a modified wet cup experiment to determine the transport of water vapor and liquid water in the plaster systems under different ambient conditions. We present a model of how the formation of a specific pore network improves the performance of hydrophilic plasters.
