SELF-HEALING CONCRETE POLE FOR CENTRIFUGAL MOLD USING SELF-HEALING INORGANIC BINDER PASTE AND MANUFACTURING METHOD THEREOF
The present invention relates to a self-crack healing concrete pole for centrifugal forming using a self-crack healing inorganic binder paste and a manufacturing method thereof. According to the present invention, the self-crack healing inorganic binder paste is formed by mixing a conventional cement mixture with blast furnace slag fine powder, which is an industrial byproduct, desulfurized gypsum, which is a byproduct of a thermal power plant, and Na_2SO_4 in a complex manner, wherein an optimal composition is derived in consideration of chemical balance of a crack width. Moreover, centrifugally forming is performed in a state of a significantly low water-binder ratio, such that a needlelike crystalline body (AFt, such as ettringite) as well as calcite are generated, thereby providing a self-crack healing concrete pole for centrifugal forming, which has a self-crack curing performance with respect to a crack having a width of 0.25 mm to be filled with the binder paste.
본 발명은 균열 자기치유형 무기 바인더 페이스트를 이용한 원심성형용 자기치유 콘크리트 전주 및 그의 제조방법에 관한 것이다. 본 발명은 종래 시멘트 혼합재에, 산업부산물인 고로슬래그 미분말과 화력발전소 부산물인 탈황석고 및 NaSO를 복합적으로 배합한 균열 자기치유형 무기 바인더 페이스트를 이용하되, 균열폭의 화학적 밸런스를 고려하여 최적 배합을 도출하고, 물-바인더 비가 상당히 낮은 상태에서 원심성형함으로써, 칼사이트(Calcite) 뿐만 아니라 침상형 결정체(ettringite와 같은 AFt)가 생성되어 균열이 충진되는 0.25mm 균열폭에 대해 자기치유 성능을 가지는 원심성형용 자기치유 콘크리트 전주를 제공할 수 있다.
