STUDY ON STRENGTH AND DURABILITY CHARACTERISTICS OF STEEL FIBER REINFORCED M40 GRADE CONCRETE

Abstract

Different types of steel fibers can be used to reinforce concrete. Steel fibers are generally classified depending on their manufacturing method. The addition of steel fibers to concrete necessitate an alteration to the mix design to compensate for the loss of workability due to the extra paste required for coating the surface of the added steel fibers. While many technical and economical advantages are benefited from using SFRC, drawbacks can also be found. They are however not likely to cause major problems. It was thought that steel fibers will have negative implications in concrete practice (i.e. transporting, surfacing, finishing etc), but experience has shown that the influence of steel fibers on these practical aspects is negligible.
This research is based on investigating the effect of different types of steel fibers on strength parameters of concrete for M-40 grade using fibers like straight fiber, crimped fiber and hooked fiber. This study is to study the compressive strength, Split tensile strength and flexural strength of steel fiber reinforced concrete (SFRC) containing fibers of 0.00%, 0.50%, 1%, 1.5%, 2%, and 2.5% by volume of cement.
