Properties of Fireproof Mortar Using Lightweight Fine Aggregate Using Air Cooling Process Bottom Ash

건식공정 바텀애시 경량 잔골재를 사용한 내화모르타르의 특성

Bottom ash generated in thermoelectric power plants could be used as substitutional fine aggregate such as pearlite of fireproof mortar due to its lightweight and porosity. Development of substitutional materials is necessary because pearlite has several problems such as production of carbon dioxide during manufacturing process and high price. This study is to confirm the possibility of air cooling process bottom ash for fireproof mortar as substitutional material of pearlite through basic experiment.
