Utilization Of PDL Cadet Clothing Waste As An Admixture For The Manufacture Of Fiber Concrete To Support Defense Architecture Building

Abstract

Military service clothing waste, especially PDL (Field Service Clothing) for Military Academy Cadets reaches more than 5,000 sets of waste every year. This condition allows the misuse of waste to be used for crimes in the name of the TNI. Material design by utilizing this waste as a concrete mixture is one solution. Fiber concrete is concrete with added fiber to obtain a higher tensile strength. The aim of the research is to obtain building materials in the form of textile fiber concrete from military uniforms (PDL clothes) which can be implemented as building materials. Quantitative research method using an experimental approach, namely by making fiber concrete with a mixture composition: cement: sand: gravel: fabric residue PDL = 1: 2: 3: 1 and testing the hardness of the concrete using a hammer tester and shooting test with an SS-gun. 2 (Assault Rifle version 2) 5.56 mm rounds and SP-2. gun (Rifle Long version 2) with 7.62 mm rounds fired at 50 m and 100 m. The results showed that PDL fabric fiber concrete is less easily damaged than standard concrete, so it can be used as a building material for defense architecture, such as guard posts and border guard houses.
