Durability of SCC: from materials to structures

Author
Organization
Abstract
As a result of different mix design, different durability characteristics could be expected for self-compacting concrete in comparison with traditional vibrated concrete. Degradation mechanisms of cementitious materials are greatly influenced by the permeability for potentially aggressive substances. As the pore structure is different for SCC in comparison with traditional vibrated concrete, some specific durability issues can be noticed. This paper is first giving an overview of hydration, microstructure, and transport mechanisms of self-compacting concrete. Afterwards, available durability results are summarized in general. Furthermore, it is investigated whether durrent code provisions concerning durability, developed for traditional vibrated concrete, are still valid in the case of self-compacting concrete. An extended experimental program was executed, focusing on carbonation and chloride penetration. The experimental results lead to the conclusion that self-compacting concrete meets the durability requirements provided in the European code EN 206-1, combining a maximum W/C and a minimum cement content. However, estimating durability properties of Self-Compacting Concrete by a mere verification of the attained compressive strength level can lead to major durability risks.
