Perancangan Sistem Uji Tekan Suatu Bahan Menggunakan Metode Half Bridge Weight Sensor Berbasis Mikrokontroler Arduino

Abstract

Concrete is a mixture of Portland cement or other hydraulic cement, fine aggregate, coarse aggregate and water, with or without additives. Concrete is a composite material. It is called a composite because it consists of a binder (usually a mixture of hydraulic cement and water), fine aggregate (usually sand) and coarse aggregate (usually gravel) with or without additives). In this study, the Arduino microcontroller was used as a control system in the measurement process. The sensor used in this study is a half bridge load cell sensor. The mechanics used in this system are manual jack mechanics. With this, research is carried out in testing automation systems and mechanical design in producing a research system with the title "Design of a Compressive Test System for a Material Using the Half Bridge Weight Sensor Method Based on Arduino Microcontrollers". By doing research, it can make an innovation and solution in the development of an efficient pressure testing tool. This metal can be grown before or after the casting process. The compressive strength of the concrete produced by the pull out test is ± 20% of the compressive strength produced by the compression test. Several testing tools in compression testing have been widely used but have high costs. The depth of penetration of the reinforcement shows the strength value of the concrete being tested. This procedure is almost the same as the hammer test, it's just the impact force. And the results of the comparison of the value measurement with the comparison, the average percent error in the above measurement is 0.81%.
