電気炉酸化スラグと発泡スチロールビーズを混練したモルタルの発泡スチロールビーズの粒径および発泡倍率が電波吸収性能に及ぼす影響

Abstract

A mortar using electric arc furnace oxidizing slags and styrofoam beads ("beads") as aggregate ("beads slag mortar") becomes a broadband electromagnetic wave absorber by vibrating before curing. In this study, the effect of varying the particle diameter and expansion ratio of the beads used as aggregate in beads slag mortar on the electromagnetic wave absorption was investigated. The larger the particle diameter of the beads, the smaller the water cement ratio and vibration time required to design a broadband electromagnetic wave absorber. On the other hand, effect of the expansion ratio of the beads is little.
