Performance Oriented Functionalisation of Concrete: An Integrated Approach for Prevention in Construction

Gerdes, Andreas; Schwotzer, Matthias; Süßmuth, Julia

Abstract (englisch):
The long-term preservation and the future-oriented development of the infrastructure are of utmost importance for every country in the world. An increasing failure of infrastructure underpins a tremendous need for action. The reasons for this unsatisfactory situation are various, but certainly among them is often an insufficient performance of the building materials. This holds particularly true for reinforced concrete and its additives, which are nowadays commonly developed by empirical research. Almost all shortcomings of concrete durability are related to the transport of detrimental substances into the pore system. In this regard, a promising approach to prevent chemical deterioration processes is a functionalisation of the pore system by means of organosilicon-based surface treatments in order to hamper the uptake of aggressive aqueous solutions. However, little is known about the reaction mechanisms and the nature of the reaction products associated with such measures. However, this is necessary to obtain reliable information about their performance and ideally to develop these technologies further in a more target-oriented ma ... mehr
