Abstract

Abstract The concrete has the advantages of high compressive strength properties and is weak to tensile strength properties. From previous research, it is known that fiber concrete can increase the tensile strength of concrete, therefore fiber concrete research is carried out using strapping band waste. With 2 size variations are used, namely the size of 40x1.5 mm and 50x3 mm. The percentage of strapping band waste for the mixture used is 0%, 2%, 4%, and 6% against 1 m3 of concrete volume. The mix design refers to SNI 03-2834-2000 using FAS 0.5. The concrete specimens is cylinder 15 cm in diameter and 30 cm in height. The test of compressive strength and spitting strength of fiber concrete was carried out at the age of 7, 14, 28 days, and the absorption test at the age of 28 days. From the tests that have been carried out, it is known that the strapping band fiber concrete with a size 40x1.5 mm has the highest compressive strength value in the 6% strapping band waste concrete, which is 31.89 MPa, and 1.05% lower than normal concrete. The concrete using 2% strapping band and a size of 50x3 mm produces highest compressive strength value of 34.10 MPa, 1.02% higher than normal concrete. The average compressive strength value is about 30 MPa, indicating that strapping band concrete can be used for structural materials. The results of statistical analysis showed that a mixture of strapping bands of about 3% to 4% will get the optimal compressive strength values. The greater the percentage of strapping band size 50x3 mm, the lower the strength of concrete. The splitting strength of the 4% and 6% strapping band fiber concrete 40x1.5 mm is 1.02% and 1.04% higher than the normal concrete, respectively. The splitting strength of the fiber concrete strapping band is 2% and 4% with the size of 50x3 mm is 1.004% higher and 1.024% of the normal concrete. The ratio of splitting strength value to the compressive strength value is obtained about 10-11% for both the 40x1.5 mm and 50x3 mm strapping bands concrete. This shows that the concrete strapping band as fiber concrete is able to increase the splitting strength of the concrete. The results of strapping band concrete absorption testing show that the higher the absorption value, the slightly effect on reducing the strength of concrete. Key words : Concrete, strapping band, fiber concrete, compressive strength, splitting strength.
