The present study is an experimental study to investigate the characteristics of strength by mixing polyaluminum chloride(PAC) with OPC-slag-FA ternary blended cement. There are three types of binders: 80% OPC + 10% slag + 10% FA, 60% OPC + 20% slag + 20% FA, and 40% OPC + 30% slag + 30% FA. PACs us...

PAC는 무엇인가? | PAC은 polyaluminum chloride (Al2(OH)nCl6-n)로 불리는 수처리 과정에서 사용되는 응집제이다. PAC은 aluminum과 chloride 이온을 포함하고 있으며 처리수의 pH에 영향을 적게 받는다. | |
PAC을 혼합한 콘크리트는 어떤 제품에 적용하여야 하나? | 또한 chloride 이온은 철근콘크리트의 철근 부식을 유발하는 위험성이 있다. 그러므로 PAC을 혼합한 콘크리트는 철근을 사용하지 않는 블록, 벽돌 등의 제품이나 섬유 (fiber)를 사용한 고인성 콘크리트, 도로 포장 등의 철근 부식의 위험이 적은 구조물이나 제품에 적용가능 할 것으로 판단된다. | |
콘크리트의 성능향상을 위한 목적으로 사용되는 산업부산물은 어떤 것들이 있는가? | 이는 과거부터 다양한 산업부산물들이 시멘트의 일부로 치환되어 콘크리트의 성능향상을 위한 목적으로 사용되어왔다. 대표적인 산업부산물로는 플라이애시 (FA; Fly Ash), 고로슬래그 미분말(Slag; ground granulated blast furnace slag), 레드머드(RM; Red Mud), 실리카 퓸(SF; Silica Fume)등이 있다. 이러한 산업부산물들은 단독 또는 다성분계까지 다양한 혼합방법으로 구성된다. |
