바닥재를 사용한 내화 뿜칠 모르타르의 내화성능 = Fundamental Study of Fire-Proof Characteristics of Spraying Mortar Using Bottom Ash

다국어 초록 (Multilingual Abstract)

The effectiveness of bottom ash applied in spraying mortar was investigated in this study to find out fire proof characteristics. Bottom ash is well known that it can make it possible to decrease the heat conduction in mortar by their porous structure. Physical properties of bottom ash including pozzolanic activity and compressive strength test were measured to decide the replacement amount in previous test. This study was undertaken on the use of bottom ash as fine aggregate in fire proofing mortar and we found out there were serious correlation between specific gravity and thermal conductivity. Based on the laboratory test results, other porous materials were also investigated to decrease the thermal conductivity of cement mortar as well as bottom ash. We'd like to suggest the proper porous material and adding amount of bottom ash by various evaluations.
