Light weight aggregate manufacturing method using organic sludge and stone sludge in combination
The present invention relates to a method for manufacturing lightweight aggregate using a combination of organic sludge and stone sludge. More particularly, the method for manufacturing lightweight aggregate using a combination of organic sludge and stone sludge can convert the inefficient treatment method of organic sludge waste and stone sludge waste, which are currently discharged as industrial waste, into an eco-friendly method of recycling as a raw material for manufacturing high value-added lightweight aggregate, and the method is improved to be widely used for lightweight concrete products such as bricks, blocks, and boundary stones, lightweight concrete such as roof-press concrete and deck-plate concrete, load-reducing materials such as roof greening, underground parking lot rooftop, retaining wall filling material, etc. by means of lightweight aggregate manufactured with excellent physical properties such as low specific gravity, low absorption rate, and high strength as well as low defect rate during manufacturing. The method of the present invention comprises a raw material preparing step, a mixing step, a molding step, a surface coating step, a drying step, and a sintering step.
본 발명은 유기성슬러지와 석재슬러지를 복합적으로 이용한 경량골재 제조방법에 관한 것으로, 보다 상세하게는 현재 산업폐기물로 배출되고 있는 유기성슬러지 폐기물 및 석재슬러지 폐기물의 비효율적인 처리방법을 고부가성 경량골재의 제조원료로서 재활용하는 친환경적인 방법으로 전환시킬 수 있고, 제조시 불량률이 낮을 뿐만 아니라 저비중, 저흡수율, 고강도 등의 물성이 우수하게 제조된 경량골재를 이용하여 벽돌, 블록, 경계석 등의 경량콘크리트 제품, 옥상누름 콘크리트, 데크플레이트 콘크리트 등의 경량콘크리트, 옥상 녹화용, 지하주차장 옥상, 옹벽뒤 채움재 등의 하중저감재 등의 용도에 폭넓게 이용될 수 있도록 개선된 유기성슬러지와 석재슬러지를 복합적으로 이용한 경량골재 제조방법에 관한 것이다.
