Abstract

본 발명은 벽면이나 천정등의 건축용 판재로써 사용되는 슬래그 보오드의 제조방법에 관한 것으로써, 고로 슬래그와 석고 및 기타 무기질재료를 이용하여 초조공정을 통해서 미반응 슬래그 보오드를 제조하고, 양생 및 건조하므로써, 직정강도를 유지하면서도 크랙의 발생이 적고 경량화된 슬래그 보오드를 제공하고자 하는데, 그 목적이 있다.
본 발명은 비정질하율이 90%이상인 슬래그 함유 배합원료를 초조방식에 의해 보오드 성형을 한 후 양생 및 건조하여 슬래그 보오드를 제조하는 방법에 있어서, 상기 슬래그 함유 배합원료가, 중량%로, 수쇄슬래그 : 40-70%, 석고 : 3-33%, 소석회 : 1-5%, 및 보강재 : 5-15를 기본성분으로 하고, 여기에 탄산칼슘 : 20%이하와 퍼얼라이트 : 20%이하를, 및 스크랩(scrap)분말 : 1-15%로 이루어진 그룹중에서 선택된 1종 또는 2종이상을 첨가하여 조성되는 초조성형에 의한 슬래그 보오드의 제조방법을 그 요지로 한다.
