Investigating Electromagnetic Shielding Properties of Building Materials Doped with Carbon Nanomaterials

Abstract

Electromagnetic (EM) shielding has become an essential element in the modern world alongside the increased use of electronic products and telecommunication equipment. We are surrounded by electromagnetic fields that have inevitably become formidable in our lives. It is possible to absorb EM waves by adding materials. Researches have focused the addition of different additives into the cement based mixture to increase the Electromagnetic (EM) shielding. This study aims to investigate the performance of carbon nanomaterial on mechanical, electromagnetic shielding properties of composite. Hence, samples were produced using obtained cement composites. After 28 days of curing, ultrasonic pulse velocity, flexural and compressive strength, water absorption tests and electromagnetic shielding were implemented for samples. As a result of this research, it was concluded that electromagnetic shielding was formed as the percentage carbon nanotube contribution increased, and electromagnetic pollution was partially prevented.
