Abstract
현재의 수분침투를 방지하기 위한 콘크리트 표면 처리기술의 단점을 보완하고 콘크리트 내부에서 부터 발수성능을 구현하기 위하여, 발수성 함침 천연 제올라이트의 혼입을 통해 시멘트 모르타르의 염화물침투저항성 및 미세구조에 미치는 영향에 대한 실험적 연구를 진행하였다. ZWR을 혼입한 시험체의 흡수율 및 침투저항 성능이 향상되어 총 통과전하량이 기준모르타르에 비해 낮음을 확인하였다. 천연 제올라이트의 포졸란 반응으로 장기적으로도 수화가 진행되며, XRD시험결과 기준 모르타르와 비교하여 결정 또는 구조적 변화의 차이가 관찰되지 않았다.
In order to complement the disadvantages of the concrete surface treatment technology and improve the durability performance of concrete, the penetration of water-repellent impregnated natural zeolite is introduced to the cement mortar for chloride penetration resistance. An experimental study on the effects on performance and microstructure was advanced. It can be confirmed that the water absorption and the permeation resistance performance of the test specimen containing ZWR are improved in proportion to the mixing amount. It was also confirmed that the permeation resistance performance of chloride was smaller than that of OPC in terms of total passing charge. In addition, it was confirmed that the hydration reaction was sustained for a long time in the pojollan reaction of natural zeolite, and no difference in crystal phase or structural change was observed with the reference mortar in the XRD test results.
