The Effect of Addition of Waste Strapping Band on Gap Graded Concrete

Natsir Abduh, Gufran Darma Dirawan

Abstract

The study aimed to determine the effect of compressive strength and split tensile strength of gap graded concrete with the addition of strapping band waste variations of 0.5%, 1.0%, and 1.5% of the weight of cement. The study was conducted at the Materials and Concrete Laboratory of Bosowa University-Makassar. Quantitative research with experimental studies through the DoE (Design of Experiment) method conducted at the Materials and Concrete Laboratory of the Faculty of Engineering, Bosowa-Makassar University. The study design was carried out on the quality of concrete f'c 20 Mpa. Normal concrete testing has a graded grade, obtained by concrete compressive strength of an average of 23.52 MPa. Gap graded concrete with the addition of fiber strapping band as much as 0.5% of the weight of cement, obtained by compressive strength of concrete at an average of 24.06 Mpa. Compressive strength of an average of 26.04 Mpa obtained the addition of fiber strapping band waste as much as 1.0%. Concrete compressive strength of an average of 20.48 MPa gained addition of 1.5% fiber strapping band waste. The concrete tensile strength of an average of 1.463 MPa gained normal graded concrete testing. The concrete tensile strength of an average of 1.557 MPa achieved Gap graded concrete with the addition of fiber strapping band as much as 0.5% of the weight of the cement. The concrete tensile strength of an average of 2.548 MPa attained the addition of 1.0% fiber strapping band waste. Finally, the concrete tensile strength of an average of 1.982 Mpa found addition of 1.5% fiber strapping band waste.
