A Study Of Behaviour Of Macro And Micro Hybrid Fibre On Performance Of Concrete

Abstract

The paper presents an experimental investigation conducted to study the effect of hybrid fibre addition to Self Compacting Concrete (SCC) and compare the flexural behaviour of reinforced SCC beams without fibres, with macrofibres and with hybridfibres. The addition of two or morefibres in the concrete named as Hybrid Fibre Reinforced Concrete (HFRC) which derives more benefits from each of the individual fibres than the Single Fibre Reinforced Concrete (SFRC). Now a day, there are numerous types of fibres made of different materials that are of different geometric properties. With each type of fibre certain properties of concrete can be improved. In order to improve mechanical properties, especially the tensile and flexural strengths and long-term concrete shrinkage, steel fibres’ are usually used. Hybrid fiber reinforced short columns were capable of carrying large amounts of strain than normal RC column.
