Lightweight foamed concrete is typically used in the insulation layer of the apartment floor. And Lightweight foamed concrete used as a refractory of lightweight panels, fireproof safe and has been used for a variety of purposes. The existing research focused on the part of the building insulation research primarily. But, for a systematic study has not been made on a portion of which is used as a refractory of fireproof safe. Fireproof safes is used to protect the securities and various documents and valuables from fire. And korea safe is high market share in the world. Therefore, this study basically using a foaming agent lightweight foamed concrete. And perlite and expanded polystyrene beads were used as the aggregate. Density, compressive strength, thermal conductivity, and fire performance tests conducted by the results presented here. And, I hope Lightweight foamed concrete has been widely used.
