Electromagnetic Shielding Characteristics of Eco-Friendly Foamed Concrete Wall
The electromagnetic shielding characteristics according to the material composition of foamed concrete, which was manufactured to reduce environmental pollution and to economically apply it in actual building walls, were researched herein. Industrial by-products such as ladle furnace slag (LFS), gyp...
