Scrap Steel Fiber Reinforced Concrete- Design & Analysis

Abstract

This paper describe the use of scrap fibres which comes from the various industries & institutes as steel fibres are much costly and their cost is increased as increasing the percentage of steel fibres in the given concrete mix. so the concept is to design a suitable concrete mix and to analyze the various properties of this particular design mix as all know the function of the fibre based concrete is to arrest cracks, fibre composites possess increased extensibility and tensile strength, both at first crack and at ultimate, particular under flexural loading; and the fibres are able to hold the matrix together even after extensive cracking but by using these scrap fibres I wish to maintain the cost of the mix and obtain the improved values of the different properties related to concrete mix.

Key Words: Scrap Steel fibres; Design Mix; Compressive strength; splitting tensile strength; Cracking; Workability.
