Comparative Study on Behavior of Self Compacting Concrete (SCC) under Static Load at Different Loading Rates

Self compacting concrete (SCC) was developed in late 1980s in order to improve the performance of concrete in its fresh state particularly when used in narrow formwork with congested steel reinforcement. The fundamental aims of the development were to enhance the flowability, self-compacting abil...
