An Experimental Study on the Fire-Resistant Performance of Extruding Concrete Panel using Crushed Stone Powder
Jisun Park
Abstract
Crushed stone powder generated during processing of artificial stone plates and stone tiles is improperly disposed, owing to the fact that many stone processing companies are small and poor, and because of rising costs for disposal by consignment. An efficient recycling and disposal plan is therefore required to address this situation. In this study, extruding concrete panels were made using crushed stone powder as a means to utilize this unused recycled resource and then the fire resistance test was performed to verify application of building materials. Fire resistance performance testing was carried out according to the current provisions of KS F 2257-1, 8. Pilot testing provided primary confirmation of the fire resistance performance of crushed stone powder substituted silica powder, and based on these results a full scale specimen was tested. Test results showed that crushed stone powder substituted silica powder sufficiently satisfied current fire resistance requirements for non-loadbearing vertical separating elements.
Key Words: Crushed stone powder; Extruding concrete panel; Fire resistance performance
요지
석재가공 과정에서 발생되는 폐석분은 가공업체의 영세성과 위탁처리비용의 상승으로 적절한 처리가 이루어지지 않고 있으며 이에 국가 차원의 효율적인 재활용 대책 및 처리방안이 필요한 실정이다. 본 연구는 이와 같은 미활용 순환자원을 활용하고자 폐석분을 이용하여 압출성형 콘크리트 패널을 제작하였고 건축부재의 기본 성능 중 내화성능을 평가하였다. 내화성능 평가는 현행 KS F 2257-1, 8의 규정한 바에 따라 수행하였으며 파일럿 시험결과로부터 폐석분 치환 패널의 내화성능을 1차적으로 확인하였고 이 결과를 토대로 실물크기의 시험체를 제작하였다. 실물시험결과로부터 폐석분 치환 콘크리트 패널은 현행 건축 재료로서 수직 비내력 구획 부재의 내화성능을 충분히 만족하였다.
핵심용어: 폐석분; 압출성형 콘크리트 패널; 내화성능
