Influence of Steel Fibers on the Account of Permeability Aspects of M20 and M40 Grade Concrete
Steel Fibre Reinforced Concrete is used in a number of applications such as ground slabs, shotcrete, pavements etc to enhance the performance of plain and reinforced concrete. The study on durability characteristics of fiber reinforced concrete is scanty and hence the study on permeability is essential. This paper deals with the study on the permeability of steel fibre reinforced concrete. Deformed Steel fibres with different volume fraction were used in this study. Permeability was observed to decrease significantly with the addition of fibres and it continued to decrease with the increase in fibre content. Permeability tests were conducted using permeability test apparatus as per IS 3085 -1965. Mathematical equations were derived to determine the permeability using the parameters, volume fraction of fibers,and age of curing.
