    Abstract

    Due to the times, the development of building structure has very rapid. Reinforced concrete structure is one that is very realible structure strenght today and widely used in the construction of high rise buildings, bridge with a lenght, and towers etc. This structure requires a high strenght concrete with compressive strength more than 6000 Psi or 41,4 MPa. The solution to improve this concrete’s strength is by adding fiber to concrete, then select the additional material copper fiber derived from wasted electrical materials wiring which is copper fiber that come from recycled useles materials to increase the compressive strenght of concrete. The purpose of this study is to determine the effect of copper fiber addition to the concrete’s mechanical properties, such as compressive strength, split tensile strength, and modulus of elasticity. The used method is an experimental method that will be conducted in the Material Laboratory of UNS. The specimen is in form of cylinder with diameter of 15 cm and height of 30 cm for testing the compressive strength, split tensile strength and modulus of elasticity. Each specimen consist of 4 pieces for 1 variation of fiber additional rate. The used fiber precentage are 0%; 0,5%; 1%; 1,5%; dan 2%. This experiment using CTM (Compression Testing Machine) tool. The used calculation is statictic analysis with linear regression on the elasticity limit of the concrete using Microsoft Excel. The result of the research is the increase of the value of high strenght concrete’s compressive strength, split tensile strength, and modulus of elasticity after added by copper fiber. The maximum increasing value is on the fiber addition rate of 1% from the concrete’s weight. The concrete’s compressive strength values with copper fiber additional rate of 0%; 0,5%; 1%; 1,5%; dan 2% adalah 41,61 MPa; 43,60 MPa; 46,43 MPa; 42,68 MPa; dan 42,04 MPa. The concrete’s split tensile strength values with copper fiber additional rate of 0%; 0,5%; 1%; 1,5%; dan 2% adalah 2,25 MPa; 2,55 MPa; 3,36 MPa; 2,90 MPa; dan 2,48 MPa. 2,55 MPa; 3,36 MPa; 2,90 MPa; dan 2,48 MPa. The modulus of elasticity values with the copper fiber additional rate of 0%; 0,5%; 1%; 1,5%; dan 2% adalah 22066,75 MPa; 24268,74 MPa; 25851,75 MPa; 22663,62 MPa dan 22106,82 MPa. Fiber additional rate of 1% resulting the increase of compressive strength, split tensile strength, and the modulus of elasticity consecutively 11,56%; 49,37%; and 17,15% compared to the high strenght concrete which has no fiber. Keywords : High Strenght, Copper fiber, Compressive strength, Split Tensile Strength, Modulus Of Elasticity
