Strengthening of RC Beam Using Synthetic Fibers and Steel Fibers

Abstract

The fibers are commonly use to enhance concrete’s flexural resilience and ductility, and can even remove the need for traditional reinforcement. Steel fibers are more commonly used in structural applications while synthetic fibers are more frequently used due to shrinkage to reduce crack opening. RC beam specimens were constructed with steel and synthetic fiber groups, based on the investigation. The introduction of admixtures was used in steel fibers of hook ends with 50, 60 aspect ratio and crimped round of 52.85 aspect ratio comprising 0 per cent and 0.6 per cent volume fraction. In the group of synthetic fibres 20 mm cutting thicknes polypropylene fibres. In order to compare the strength aspects of RC beams using synthetic fibers, steel fibers with those of traditional RC beams, this paper validated the positive effect of steel fibers with different aspect ratios and polypropylene fibers with different cut lengths in compression and splitting performance improvement of specimens at 7 and 28 days, examined the sensitivity of different fibers to concrete with flexural strength.
