Utilization of Strapping Band Waste for Reviewed Mortar Againsts Compressive and Split Tensile Strength

Abstract

The aim of the study was to make mortar with a fiber mixture that utilizes band strapping waste. The selection of strapping band material as fiber since this material is not environmentally friendly, the benefits of this research can reduce band strapping waste and increase the economic value of band strapping waste. This research was conducted to determine the optimum fiber concentration value which resulted in the value of split tensile strength, compressive strength of maximum mortar, fiber strapping band with a length of 50 mm and width of 2.5 mm in the composition of 0%, 1.25%, 2.5%, 3.75%, 5%. The size of the specimen is 150 mm in diameter and 300 mm in height for the split tensile strength test and the object size is 100 mm in diameter and 200 mm in height for the compressive strength test. The number of specimens is 35 pieces, with each composition as many as 3 samples. For compressive strength test using 15 test specimens and split tensile strength test using 15 test specimens. From the test results, the optimum composition occurs in 5% fiber strapping band with a maximum increase in compressive strength of 29.67% (40.3 Mpa), split tensile strength of 60.94% (1.03 Mpa). For volume weight of 100 × 200 mm decreased by 7.58% (1.955 gr / cm3) while for weight volume 150 × 300 mm decreased by 3.62% (1.868 gr / cm3). Due to the increased split tensile strength, this mortar mixture is suitable for the manufacture of plastering or mortar on the surface of the wall especially the outer wall.
