Ductile Behaviour of Fiber Reinforced Self Compacting Concrete Beam with Alternative Detailing

Abstract

Self-compacting concrete is one of the major advancements in construction. The purpose of this investigation is to evaluate how self-compacting concrete with steel fibres and the appropriate superplasticizer for M30 grade is presented. Effects of combining quartz flour 0 %,5 %,10 %, 15 %, 20 % and steel fibre 0 %,0.25 %,0.50 %,0.75 %, 1 % in varying amounts adding with cement. An experimental study was conducted on the fresh and hardened states of concrete. The optimal combination of quartz flour and steel fibre reinforced concrete was discovered while comparing the mixes to conventional concrete. Quartz flour with ultra-fine particles can fill holes and improve permeability resistance as well as bonding. As a result, utilizing this combination of quartz flour in self-compacting beams, studies explored the strength and ductile properties of normal and ductile details in beams, as well as comparing them to standard self-compacting concrete. Because self-compacting concrete is brittle by nature, adding fibres increases its tensile strength and ductility. Mineral admixtures improve the flow qualities.
