Abstract
In the last several years, self- compacting concrete (SCC) has gained considerable attention in the concrete industry in order to overcome the problems associated with conventional vibrated concrete (CVC). The concept of SCC was originally advocated by Japanese researchers in the early 1980s and shortly thereafter developed and introduced as a construction material [1-3]. The term “self-compacting concrete” refers to a “new” special type of concrete mix characterized by high resistance to segregation that can spread into place, fill the formwork, and encapsulate reinforcement without any mechanical consolidation [4-5]. Such concrete should have a relatively low yield value to ensure a high degree of flowability and a moderate viscosity to resist segregation and bleeding. Furthermore, it must maintain its homogeneity during transportation, placing and curing to guarantee adequate structural performance and long-term durability. The successful development of SCC should be characterized by a good balance between deformability and stability. Researchers have established guidelines for the mix proportioning of SCC,
