Self-Compacting Concrete: Materials, Properties, and Applications
Abstract. Self-compacting concrete (SCC) is design to achieve three functional requirements, which are filling ability, passing ability, and resistance to segregation. These requirements are necessary to properly fill the formwork and adequately encapsulate reinforcing bars only through the action of gravity, while maintaining good homogeneity.
