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.

Recently the generation of industrial byproducts has been increased by increase of consumption of electric power. One of the significant byproducts need huge amount of re-utilization is known as bottom ash and many studies to find out appropriate application have been performed and reported. In this work, the physical properties of bottom ash generated from power plant are analyzed. Characteristic mortar property for building material were investigated with content of added bottom ash and various lightweight aggregates. According to the analytic result of 22.5% of bottom ash with 5% of Expan cel, chemical compositions of bottom ash is similar to those of fly ash and compressive strength after 7days related to pozzolanic activity shows 19.6N/cm2.
