Plain concrete has a very low tensile strength, limited ductility and little resistant to cracking. Internal micro cracks are present in the concrete and its poor tensile strength is due to the propagation of such micro cracks, leading to brittle fracture of the concrete. In the past attempts have been made to improve the tensile properties of concrete by way of using reinforced steel bars and also by applying restraining techniques. Although both the two methods provide tensile strength to the concrete members but do not increase the tensile strength of the concrete. Then Steel fibres are used to increase the tensile strength of concrete. The cracks present in the concrete will be controlled by adding coir fibres to the concrete. The study aims to evaluate the properties of concrete using steel and coir fibres. This project presents adding steel and coir fibres to the percentage of 0.5, 1.0, 1.5, and 2.0% to the weight of the concrete. Physical and chemical properties of steel and coir fibres have been studied. A concrete mix has been designed to achieve the grade of M30 as required by IS 10262-2009.The investigation contains two phases. The phase one contains to study and determine the properties of the material. In the phase two contains to determine the Compressive Strength, Split Tensile Strength and Flexural Strength of the concrete at 7, 14 and 28 days by adding steel and coir fibres to the percentage of 0.5, 1.0, 1.5 and 2.0% to the weight of the concrete.
