Abstract—Self Compacting Concrete (SCC) has become synonymous with the construction industry due to the inherent advantages it possesses such as strength through durability, reasonable cost of ingredients, adoptability for all types of moulds, architectural construction with aesthetic sense, better fire resistance and weather resistance. The development of SCC marks an important milestone in improving the product quality and efficiency of the building industry. The typical methods of compaction and vibration of normal concrete generates delays and additional costs in concrete. A structural reinforced concrete member can be theoretically analyzed, if the stress- strain behavior of its constituent material is known. This paper aims to develop stress block parameters for predicting the stress-strain behavior of Fiber Reinforced Self Compacting Concrete (FRSCC). The results of specimens tested under strain control rate of loading are presented. The behavior of tie confined FRSCC is used in formulating a constitutive relationship. 

Index Terms—self compacting concrete, glass fiber, confinement index, fiber index, stress block parameters, stress-strain relationship
