TO STUDY THE FLEXURAL BEHAVIOUR OF NON-PRISMATIC BEAMS USING SELF COMPACTING CONCRETE

Abstract

Self-compacting concrete (SCC) is a type of concretethat consolidates under its own weight without external compaction. The extremely fluid nature of SCC makes it appropriate to use in difficult conditions and in sections with congested reinforcement.Non prismatic beams have non uniform cross section and so congestion arises due to closely spaced stirrups and bars. Compaction by vibrator is difficult, to overcome this beam are studied with self-compacting concrete. The present paper focuses on investigating the characteristics of M50 grade of self- compacting concrete where cement is replaced with ground granulated blast furnace slag (GGBS) and Micro Silica (MS) with six different proportions. Fresh concrete properties of the concrete were studied. Cubes and prisms were casted and tested to obtain the optimum proportion. This is further used in fabrication of non- prismatic beams. Flexural behavior of these beams are tested and compared with that of the conventional beam
