Concrete is a material which is made up of cement, water, fine aggregate and course aggregate that has excellent compressive strength and weak in tensile strength, In order to provide tensile strength usually we will provide steel reinforcement. There are many approaches to decrease the failure of concrete structures made up of steel reinforcement. The usual approach is to adhesively bond fiber polymer composites onto the structures. This further helps to increase the toughness and tensile strength and increase the cracking and deformation qualities of the resultant composite. The process involved in this project is to prepare mix design of M30 grade concrete, to conduct slump test, preparing samples with and without fiber, cubes, beams, cylinders were casted. Here we have added polypropylene fiber. It is a discontinuous short fiber that can be used in concrete to control and arrest cracks. And also we are replacing the cement by fly ash in certain percentage. The main objective is to increase the compressive strength, tensile strength by adding 0.25%, 0.5%, 0.75%, 1% and comparing with the conventional concrete. The test were conducted after 7days, 14 days and 28 days of curing.

Concrete cubes, concrete cylinder, concrete beams, experiment and finite element analysis.
