초록

경북 대포 지역에서 채취한 제올라이트의 시멘트 혼합재료로의 이용 가능성을 검토하기 위하여 제올라이트가 함유된 시멘트의 수화 특성을 연구하였다. 제올라이트가 함유된 시멘트 페이스트에 대하여 수화발열 속도, XRD, EDS, 질소 흡착, 수은 침투 등의 분석을 수행하였다. 제올라이트가 함유된 시멘트 페이스트에서는 제올라이트 양이 증가함에 따라 응결시간이 빨라지고 시멘트의 수화가 촉진되는 경향을 나타내었다. 제올라이트가 함유된 모르터에서는 제올라이트 양이 증가함에 따라 플로우가 크게 감소하였다. 또한 플레인 모르터와 비교하여 단기에 강도증진이 나타났다. 이러한 결과는 시멘트의 수화시 알칼리에 의한 제올라이트의 탈알루미늄 과정에서 제올라이트 입자로부터 이탈한 활성 알루미늄 종과 관련이 있는 것으로 보인다.

Hydration characteristics of cement containing zeolite mined at Daepo in Gyeongbuk province were studied for use as a mineral admixture. The cement paste containing zeolite was characterized by the measurement of heat evolution, XRD, EDS, nitrogen adsorption and mercury intrusion porosimetry. The cement paste containing zeolite exhibited tendencies toward acceleration of paste setting and promotion of cement hydration with the increase of zeolite content. The flow of mortar containing zeolite strongly reduced with increase of zeolite content. Compressive strength of the mortar containing zeolite increased very rapidly at an early age in comparison with plain mortar. These results would be related to aluminum species escaped from zeolite particles during the alkali dealumination of zeolite by the hydration process of cement.
