DESIGN OF SELF COMPACTING CONCRETE FOR DURABILITY OF PRESCRIPTIVE VS. PERFORMANCE-BASED SPECIFICATIONS

Self-compacting concrete (SCC)'s development offers highly interesting evolution of concrete construction, in turn leading to an improvement in the quality of finished structures and increased productivity. A key factor in achieving suitable self-compactibility properties is a better understanding of the rheological properties of mortar and concrete in its fresh state. A moderately-viscous paste prevents blocking and segregation, while a highly fluid concrete eliminates the need for external compaction. Other than the clear advantages of SCC in the fresh state, there is experimental evidence of an improvement in some properties in the hardened state as well, when compared to conventional concrete of the same strength class. This paper is aimed at showing some of the results achieved, related to the durability of this type of high performance concrete.
