PERBANDINGAN KEKUATAN BETON DENGAN CAMPURAN DRAMIX STEEL FIBER DAN TULANGAN WIREMESH PADA RIGID PAVEMENT (Comparison of the Strength of Concrete with a mixture of Dramix Steel Fiber and Wiremesh Reinforcement on Rigid Pavement)

Abstract

ABSTRACTConcrete has a weakness that is having a low tensile strength and brittle so that the concrete is given steel reinforcement to anticipate it. In this study, the concrete mixture was added with dramix steel fiber. This addition was carried out to study and determine the effect of dramix steel fiber on compressive strength, flexural strength on normal quality concrete with the addition of 0%, 10%, 20% and 30% in compressive loads. Compressive strength specimens in the form of cylinders with a diameter of 15 cm and a height of 30 cm and bending strength test specimens in the form of blocks with a length of 60 cm, width of 15 cm and height of 15 cm. Testing is done after 28 days. Concrete with the addition of dramix steel fiber is 30% more capable of producing a higher compressive strength than the others. The addition of dramix steel fiber resulted in an average compressive strength of 0%, 29.07 MPa, 10%, 29.33 MPa, 20%, 29.40 MPa, 30%, 29.58 MPa. For the highest flexural strength of concrete in the 15/15/60 beam sample, that is in the concrete mixture and the addition of dramix steel fiber of 5.44 MPa, it is higher than the addition of reinforcement iron m8, which is 4.96 MPa.Keywords:Dramix Steel Fiber, compressive strength, concrete flexural strength, m8 wiremesh
