Structural Performance of Self Compacting Fibre Reinforced Concrete

This study investigates the Structural Performance of Self Compacting Fibre Reinforced Concrete. Fibres are able to bridge cracks and to improve the ductility. Therefore, the addition of fibres might extend the possible fields of application of self compacting concrete, which has to satisfy minimum three characteristics such as passing ability, filling ability and segregation resistance. Superplasticiser is an essential component of Self compacting concrete to provide the necessary workability. In this study we have made self compacting concrete (SCC) and self compacting fibre reinforced concrete (SCFRC) satisfying above three characteristics with Superplasticisers Sulphonate Napthalene Formaldehyde. Filling ability was checked by using Slump flow and V-funnel tests. Passing ability was checked by using L-box and U-box tests. Segregation resistance was checked by using V-funnel after 5minutes. The mechanical properties of SCC were determined and the same were compared with SCFRC
