Abstract:  The term Concrete Mix Design is the methodology of selecting suitable materials of concrete and finding out their relative amounts with an objective of generating a concrete of the required characteristics such as strength, durability, and workability in an economical manner. The required concrete proportioning of ingredient is directed by the performance of concrete in 2 stages i,e the plastic and hardened stage. The plastic concrete cannot be properly placed and compacted if it is not workable. Therefore workability as a property of concrete has a vital importance. In hardened concrete, the compressive strength is generally considered to be an basis of its other properties, depends upon many factors, e.g. quality and quantity of cement , water and aggregates; batching and mixing; placing ,compaction and curing. The aim of this study is to evaluate the mechanical performance of M 40 grade concrete containing fly ash and 1 % of steel fibers. The test on mechanical properties of concrete i,e compressive , tensile and flexural strength being carried out, on concrete is conducted for 7,14 and 28 days of cured specimen for both the fiber reinforced and the conventional concrete. The study gives clear picture regarding the effect caused by the addition of steel fibers and fly ash compared with that of the conventional concrete.

Keywords:  Fly ash, Compressive strength, Split tensile strength, flexural strength.
