THE EFFECT OF PARTICLE SIZE OF COPPER SLAG USED AS AGGREGATE ON COMPLEX PERMITTIVITY AND COMPLEX PERMEABILITY OF MORTAR MIXED WITH COPPER SLAG THROUGH FREQUENCY BAND AROUND 2.45GHz

Key Points

• This research aims to evaluate the impact of copper slag particle size on the electromagnetic properties of mortar used in construction.
• Developed electromagnetic absorption material using copper slag as aggregate.
• Tested samples within a frequency range of 1.70 to 2.60GHz.
• Analyzed the influence of copper slag particle size on complex permittivity and permeability.
• Found that larger particle sizes of copper slag resulted in higher complex permittivity.
• Demonstrated that changes in particle size affect the electromagnetic absorption characteristics of the mortar.
