Self -compacting concrete (SCC)

Advanced building materials Dr. Manolia A. Ali 1 Self -compacting concrete (SCC) 1. Introduction: Self -compacting concrete (SCC), also known as self –consolidating concrete, is a highly flowable and non-segregating concrete that can spread into place, fill the formwork and encapsulate the reinforcement without any mechanical compacting Fig. (1): Self- compacting concrete (SCC) 2.Growth and development of SCC • Self- compacting concrete (SCC) was first developed in Japan in the year 1980, by Professor Hajime Okamura of Kochi University of Technology, Japan . • During his research, he found that the main cause of the poor durability performances of Japanese concrete in structures was the inadequate compacting of the concrete in the casting operations. • By developing concrete that self- compacting, he eliminated the main cause for the poor durability performance of their concrete. • By 1988, the concept was developed and ready for the first real- scale tests • Though SCC was first developed to overcome the deficiency of the skilled man power, subsequently it is observed that SCC not only
