Pembuatan dan Karakterisasi Beton Enkapsulasi sebagai Thermal Energy Storage pada PEG 6000 dan Magnetite Fe3O4 (50%, 50%) (60%, 40%)

Abstract

The study showcases the results of testing concrete with Phase Change Material (PCM) using mass variations of PEG 6000 (50%, 60%) and Magnetite Fe3O4 (50%, 40%). This research also uses physical and mechanical tests in the form of FTIR, VSM, SEM-EDX, DSC, Bomb Calorimeter, Compressive Strength Test and Temperature Distribution Test. Making physical test samples was made by mashing Magnetite Fe3O4 and PEG 6000 using a spatula. The next step was mixing the mixture and weigh it on analytical scales using beakers. Then melt it in an ultrasonic bath until the sample is homogeneous and then use 10 minutes for a solid sample which will later be tested physically. For mechanical tests, concrete was made and waited for 28 days until it was solid which later the mixture of Magnetite Fe3O4 and PEG 6000 was put into concrete and tested for temperature distribution using a thermocouple, arduino, heater, thermal camera and computer as input and output. This research considers several heat transfer matters such as conduction heat transfer and convection heat transfer and better mass variations.
