초록
잔사회와 준설토를 효과적으로 자원화하기 위하여 8~10 mm 크기의 구형 인공 골재를 성형하였다. 출발원료는입도 및 조성을 변화시켰으며 1050~1250oC 범위에서 소결하였다. 제조된 골제는 KS에 의거하여 골재의 밀도와 흡수율 시험을 진행하였다. 잔사회와 준설토는 고온에서 철 함유 물질과 알칼리/알칼리토 산화물에 의한 발포 기구가 적용됨을 예측할 수 있었다.
Abstract
To effectively utilize resources of reject ash and dredged soil, globular shape-formed artificial lightweight aggregate were manufactured in 8~10 mm size. Starting materials were changed various grading and composition, sintered at 1050~1250oC. The specific gravity, water absorptance of artificial lightweight aggregates were measured on the basis of the KS. In this study could make a prediction about application of bloating mechanism by ferrous materials and alkali/alkali-earth oxide at high temperature
