Concrete is one of the principal materials for structures and it is widely used all over the world. In any case, the heterogeneous structure of solid outcomes some unfortunate impacts.The most spectacular disadvantage of concrete may be thought as its exceedingly complex structure, which results many internal stress concentration zones. Thus, some internal micro-cracks mostly occurred in fresh or hardened state in concrete. Such micro-cracks exist at cement paste–aggregate interfaces within concrete even prior to any load and environmental effects. once concrete is subject to fast or impact loading it will suffer failure because it is inherently weak in tension. The inclusion of fibers may go some way to mitigate this weakness. It is also reasonable to produce concrete using admixtures such as Brass Coated Micro Steel fibre and Polyester fibre. The experimental work is carried out on M70 grade concrete by adding 0.5%,1%, 1.5%,2%,2.5% and 3% of Brass Coated Micro Steel Fibre and Polyester fibre . From the experimental study, it is observed that the compressive strength and flexural strength increase with control mix.
