Abstract

본 발명은 건축용 자재로 널리 사용될 수 있는 광택면을 가진 타일상의 건자재를 염기도가 높은 슬래그를 이용하여 제조하는 방법에 관한 것이다.
본 발명은 CaO와 MgO 함량의 합이 Al2O3와 SiO2함량의 합에 비해 중량비로 2.5~5.0배인 슬래그를 준비하는 단계; 1.0~8.0mm의 입도를 갖는 입자의 함량이 30-45중량%이고, 그리고 0.1mm 이하의 입도를 갖는 입자의 함량이 15-35중량%가 되도록 상기 슬래그를 분쇄하는 단계; 상기와 같이 분쇄된 슬래그 중의 잔류철분이 1.0중량%미만이 되도록 탈철선광하는 단계; 상기와 같이 탈철선광된 슬래그를 2kg/cm2의 압력 및 2시간의 오토클레이브 처리후 중량 증가율이 1.0중량% 미만이 되도록 수화처리하는 단계; 상기와 같이 수화처리된 슬래그 60-80중량%와 나프타린 설폰산 나트륨을 0.2~4.0중량% 혼합한 포오틀란트 시멘트 20-40중량%를 물과 함께 혼련하는 단계; 상기와 같이 혼련된 혼련물을 성형틀에 주입하여 성형한 후 성형틀내에서 12-48시간 동안 양생하는 단계 및 탈형후 72시간 이상 공기중에서 양생하는 단계를 포함하여 구성되는 슬래그를 이용한 건자제 제조방법을 그 요지로 한다.
